Gun progression errors.

I recently achieved lvl 23 on the M123K which should have unlocked the Long Suppressor. However, it didn't. I captured this screenshot to show the issue:

I had heard that restarting BF6 may solve the issue so I did. However, after doing so, I found that my gun level had reverted back down to lvl 22:

This may be completely unrelated, but I just started running with the thermal optic. There seems to be another bug (that I have also experienced) where you see thermal imaging intermittently on regular optics that do NOT have thermal imaging.

I read one theory (likely YouTube or Reddit) that if you were revived by someone using a thermal optic, your optic would share the thermal view if they were ADS with their thermal scope the same time you were ADS.

This made me wonder if scope imaging settings are being confused between players, is it possible that gun progression XP may also be assigned to the wrong player too if thermal optics are involved (as in my case)? I also play primarily support so I would fall into the group of players using a thermal scope and reviving others FWIW.

That may have nothing to do with the problem but thought it worth mentioning. I would love some feedback here if there is a solution or workaround. Regardless I hope it gets fixed soon.

Thanks.
