Is there any reason why the language of a part tree would cause a part not to be able to modify? I have a part that was originally done in Chinese but won't let me do any mods.
No. But do you have write-access to that particular part? You can check by looking and your PDM, or simply open it and see if it opens as 'read only'. You can see that at the top of the screen.
It seems to have write access.
I can't be sure of the language issue.
Can you do a save as copy and open, then make changes?
No can't make any changes.
