[BUG?] T-UGS mastery progressed itself for no reason

So I've noticed my T-UGS mastery is currently at 706/4000 towards T1. This is weird because I don't even play recon that much and when I do I never use it. I don't think I ever used it in 2042, let alone got over 700 enemies spotted with it.

I'm not even sure how it happened tbh. Might want to look into it before I get T1 without ever using it
