[2020] Issues with leveling an need some info please.

I started playing battlefield again after they fixed some issues that I had with the game as a whole (we all know what most where, not going to get into that now). I am level 20 with the support class, but still dont have level 8 guns unlocked. Where do i go to get this fixed? I am leveling the rest of the classes and all the guns opened (for the low levels that where not open) after I leveled one level. Any help would be awesome! Thanks in advance folks. I'm on PS4 handle is Vex-Frinj
