I'm having this problem too, although I'm not sure it is a bug exactly. I read the version update notes and, from what I could tell, it said there that this labelling system is a fallback for cosmetics that don't have their localisation done (or done a certain way, I'm not 100% clear)

Regardless, I would love to have my part names back.

I'm pretty new to modding the game. I just came back from the long hiatus specifically to try modded xcom 2, so I'm far from an expert on the subject. I've been slowly learning how to mess with config files to get mods to do what I want, so maybe I'll find some kind of solution.
