Pistol not visible in customization screen

For some odd reason i cannot see my pistol in customization screen if i have my sg553 as primary weapon.

It just shows my primary weapon in the pistol customization screen.

If i then select another primary weapon and go into my pistol customization, then the pistol shows up.

Is this something that happens to everyone? Is it just with the sg553 or do other weapons also "glitch" like this?

Haven't played BF4 for about 1 or 2 years now i think, and just as a side note... The new UI... Wow it's bad and makes no sense. Can't even customize weapons in the menu. But whatever.

EDIT: So apparently there are only 3 primary weapons that i can chose in order to be able to see my pistol in the customization screen.

All the pics bellow shows that nearly all my primary weapons are showing up in the pistol customization screen instead of the pistol.

And i just installed the game yesterday with all the expansions.

Friend of mine is playing with me and apparently he doesn't have this issue...

I'll try and see if it's because of the support class or if there's just something really weird going on with my game.

Makes no sense to me all of this. Any help or ideas are appreciated.
