NX keeps creating expressions that are referenced by non-existing/invisible expressions

[billysprocket88]

Hi

I have created a Part Familly master with a bunch of expressions in it.
There is a few of them that I did not create and they are referenced by expressions that don't exist. ( see attached file picture ).
The thing is that I can't delete them.
Even though they don't do any harm I would like to get rid of them to have a clean file.

Have you ever see that ? Do you know a way of deleting those ?

I hope my explanation are clear.

Thank you very much

I had once the same problem (NX9). The 'ghost' expressions kept popping up as 'user defined' and I couldn't delete them. Quite annoying! File cleanup did not help either.
So yes - I have experienced it. But I don't know a solution. I just ignored it.

Yeah same thing here part cleanup does not do anything!

Thank you very much for your answer! Have a nice one

If you have an example like this, Pleas contact GTAC and have them look at it since either this shouldn't be happening or at least part clean-up should clear theses sorts of things.
