What exactly is the issue here though? There's nothing wrong with your drawing, or your terminal strip, that I can see. All the information is correct. Is it just that you don't understand why some of that info is showing up in TSE? I'll explain some of it to see if that helps.
Trond isn't wrong...but wire sequence isn't really a thing for NFPA-style drawings, which yours appear to be. I'll outline what I think you could do differently below. (Again, I really don't think there's anything wrong with your drawing. It's schematically correct. But there are ways to represent terminals on a bus that help the schematics reflect real-world wiring a little more accurately.)
First though, answers to your questions.
1. Follow the wire that leaves the L terminal on DV2050. The first thing that wire encounters is a wire dot. Then, above that is a terminal block, and below it is a terminal block. Each of those terminals is showing up in the TSE as being connected to DV2050, because they are (they're only separated by that wire dot, not a component). That's why you see DV2050 listed twice. This isn't an error; it's just a reflection of how the schematics are drawn. This also applies to the N side of DV2050.
2. For this one, the thing to remember is that even though the column says 'device', what actually lands there is the TAG attribute information of the first schematic component encountered by the wire when it leaves the terminal. Sometimes that component is a terminal block, and so that's why you're seeing the terminal's strip tag showing up in TSE. Again, not an error, just a reflection of how the schematics are drawn.
Second, can you clarify something? You said 'single tb and it's two wires per side'. Does that mean two wires per connection point? It's important to remember that ACADE has no way of knowing how many connection points exist on a terminal block. All it knows is how many wires can land on the terminal block as a whole, on a level-by-level basis. So, if you have a single level terminal block, with two connection points, that can each accommodate 2 wires, then that is actually a 4-wire terminal. This subtle distinction in terminology can cause TSE to add in extra terminals because it leads us to underdefine the wires per terminal. These added terminals are what Trond was talking about.
Here's what I would do differently from what you did. Do you know about JUMPER wires in ACADE? Any wire layer with that word in its name absorbs special properties. In effect, it will carry a wire number, but will be ignored for things like wire reports and device connections in TSE. If you want to more accurately represent connections to terminals in your schematic, you'll need to put some of the existing wires on a jumper layer, to reflect the fact that you've got jumpered terminal blocks in real life. In your case there are multiple options. You could make the short wires between the L terminals and the vertical bus wire be on the jumper layer. You could make segments of the bus wire itself be on the jumper layer. Most likely, it would need to be a combination of both, and you'll have to play around with which wires to move to the jumper layer in order to get closer to a real-world terminal strip.
Another thing that helps the TSE spit out more real-world-accurate terminal strips: kill all your wire dots. Or at least, as many as you can. Remember that a wire dot is a super-generic symbol; all it represents is that two wires or circuits are connected. This can be literally anything: a wire nut, a soldered connection, a crimp splice or tee...it's a long list. However, in the industrial schematic world, a wire dot almost always means a terminal block. So, if you draw a terminal block right next to a wire dot, it's really adding a redundant symbol...they are both standing in for the same thing. That can be streamlined by replacing wire dots with terminals.
In the attached image, I'm showing the neutral side of a 120V bus. You can see that I placed my terminals directly on the bus (I'm pretty sure I edited the symbol so that I could do that though). The dark wires in between terminals are on a JUMPER layer. The terminals are single-level, with two connection points, and we often use double ferrules so we can land two wires on each connection point. So, for this terminal, I defined it to accept 4 wires per level.
I'm not sure if any of this helps you. But feel free to post back with any questions you have. TSE can be a little tricky to get a handle on.
