EBLC-RAM unlock is blocked

I have an issue that EBLC-RAM unlock progress is stuck on the 1733/2500 damage dealt and to be clear that I've dealt enough damage with required vehicles wich are EBAA Wildcat and MAV, I've unlocked everithing for MAV and some part of weapons for EBAA, but reqirement to do 2500 damage with mentioned vehicles is not complete. Can someone plese help me with the problem?
