Mutagen in inventory not applying to pool

I picked up some mutagen from a box and switched the inventory over to someone who could carry more. everything i passed over didn’t show as something gained, Mutagen container was still in soldiers inventory on global screen not able to add it to pool.
dont pass containers between soldiers in mission.

Quick fix would be to give a button on the containers to add the mutagen to the pool on Global.

Same happened me but tech. Just send the bug with f12.
