Spurious data in parameters table

[R4SMEs]

I was reviewing data in the parameters table for my model and note some spurious data.

"Extrude4" is seen in the screen save, yet there is no such extrusion feature in my model.
Quite possibly there previously was such a feature but it was deleted some time ago.

Presumably this should be logged as a bug, i.e., the fact that the parameters table is not properly consistent with the current model.

It does not appear to be possible to delete this spurious feature/ the associated parameters from the parameters table.

@R4SMEs - if you share the model here, we can take a look.  There are scenarios where parameters are retained, usually if they are used in an equation, and there may be cases where they are kept around improperly.

I wrote when I was at V94 - now I am at V100 and the issue I reported with the spurious parameter seems to have gone away.
I attach both V94 and V100.
I actually did very little between these two saved versions.

It would be interesting to understand what action was necessary for the parameter issue present in V94 to go away.
I recall doing things like Modify ... Compute All without achieving a solution.

There is another issue in that I am unable to Delete the group in the timeline entitled "M&Ts for Rear Legs/ Backrest".
I was wanting to Delete that group but retain its items for the purpose of adding another item in the group before recreating the group.
When I right click, a long list of the possibilities appears, which includes "Delete" but nothing happens when I click on the "Delete".

Located near the centre of the timeline with the green/ yellow/ pink coloured bar along the top of the timeline item.

Interesting, when I do the same for other groups in the timeline, the list of possibilities is much shorter, whilst "Delete" functions as intended.
So the question also arises as to why there are different possibilities associated with different groups?

For the offending group, despite it having the longer list of possibilities when right clicked, there is no "Expand group" in that list of possibilities - in that sense it is not behaving as a group, although it can be expanded/ contracted by toggling the -/+ sign.

Fillet edges of the cushion (at the end of the timeline) was originally working okay but has become red by V100 😞

At some point I've reported a bug, that parameter names are not updated correctly, if the feature touches more than one component. I would guess that this is the case here.

@R4SMEs - there is something strange with this design, certainly.  I see the two problems you reported here.  I've never seen either one of them before.  We'll take a look and get back to this thread.

In relation to V94 and the spurious parameter issue, a possible clue is that - for that version - the seat rebate was incorrectly slightly cutting the right rear leg.

If you turn off the "Side aprons", you will see a small horizontal rectangle on the forward face of the right rear leg which is not present on the left leg.

The extrusion (cut) used for the rebate for the plywood seat (which is named "Seat rabbets cut in rear apron and right Side apron") extends downwards by seatRabbetDepth and upwards by seatRabbetDepthUpwards.
The reason for it extending upwards is because the top of the side rail is not horizontal so an upwards extrusion was necessary to fully form the rebate in the rear apron.

At V94, the right rear leg had been incorrectly included in the selected items (Side apron and Rear apron) being cut by this upwards/ downwards extrusion.

The fact that the offending "Extrude4" is -5mm is the same as the 5mm value of my seatRabbetDepthUpwards user parameter is probably not coincidental.
