As title, after I've deleted an unnecessary .STEP file from my main assembly, before deleting the part inside solidworks, I can't delete it inside my assembly.

Here's a screenshot of what I see, It's like a suppressed model but I'm unable, of course, to unsuppress it but also I can't delete it. I'd like to remove this part from assembly list since it's not necessary.

I've tried to search on forum and:

- I can't delete the file since there isn't this option (right click);

- I can't unsuppress;

- I can't break links because I don't have this option (right click);

- I can't restore the file since it was custom generated and I can't reproduce it.

Any idea on how to solve this problem?
