Weapon Mastery not progressing for certain weapons

Only for the G57 pistol and the GOL Magnum, I am stuck at exactly halfway through the Tier 2 Mastery stage (360/720 kills) for both weapons. Other weapons and operator mastery progressions are working fine, both new and old.

I have attached files of the weapons with issues, and an example of a weapon that isn't experiencing this issue.

I know Season 5 started with an issue with operator stats, but it seems that this issue is still persisting. I believe I had both the G57 and GOL at exactly 360/720 before the update - it's not that they both suddenly stopped progressing at that point during a game.

I've tried verifying files/reinstalling but no luck. Any help would be appreciated.
