MTAR-21 unlock progression with A-91

I have this happening to me with the CAV Brawler.  Any kills assists or spawns i get with the crawler are not being recorded.  i don't know if this is related, but i've achieved everything to unlock both the m39 emr and the SVD, however only the m39 emr is unlocked and usable. When i scroll over the SVD, it shows that i have achieved all necessary requirements to unlock, including all necessary requirements to unlock the m39.  All these issues began at the start of week 3. I had achieved all requirements for SVD but not yet for the m39 before week 3. Maybe the latest patch had something to do with it?
