i am having trouble selecting secondaries as primary's i started a new game i now have an Iridar's Akimbo Class solder it auto equips a pistol primary but i am unable to re-pick using custom pistols or even seeing the base one i still need to get more troops up with other classes to use as such any ideas why this is happening or how to fix it?

Edit:
got a samuri the same thing i can pick secondary but not primary.
