Pipes in Profile Display Incorrectly

[nkg2]

Not a big issue, but I was just curious to know what I am looking at.  I have drawn in essentially a sewer pressure pipe (using gravity part network because I don't have time to setup the other) and I am using PVC pipe and null structures at the joints.  I created the pipe network from a feature line with verticies at the grade breaks and every 10'.  As you can see in the picture the pipes are lining up but I have these straggling lines on the profile.  Any idea what this is and maybe how to get this fixed.  No a pressing issue, just curious.  Thanks!

Possibly the "Pipe End Lines" display is on in the "Profile" view direction of the pipe style in use.

Yeah I checked the style for both the null structure and the pipe ends and both are turned off.   Kind of bizarre.
