GEW and MTAR not tracking

The GEW-45 and MTAR-21 weapons are not tracking in the weapons section. I can see that the specialist’s kill count is going up, so I know that that’s tracking. But whenever I use those weapons, which I haven’t used before, there’s nothing new added to my weapons list stats.

I also noticed that the RPK and the XCE Bar are both missing from the weapon tracking list.
