I chose a ballcap option in my loadout 2's head slot. It automatically put it on my head in loadout 1 as well.
My loadout 1 headslot selection was 'none'... but I was unable to clear the ballcap from loadout 1 to my normal head. Sure I could have another cosmetic headpiece, but that was not my choice.

Not a big issue. Clearly this can wait, but it will remain annoying until it's sorted. I like to be able to have every loadout look DIFFERENT so it's VERY apparent what class this is I'm playing at a quick glance.
