I think I got it (LWM's Deep Storage) working/found a way around the problem, let me rather say it's working consistently in my current settlement.
It appears there's some issue LWM's<->Combat Extended.
When I find a pawn stuck in the infinite loop of adding and removing an item into one of the LWM's storage units it appears it is by a pawn with a new/uncompleted CE loadout gearing.
So what I do is, whenever I assign the first loadouts, whenever I change a pawn's loadout or whenever I find a pawn stuck in the loop I click the Rearm button for that pawn and babysit them through equipping themselves. The might want to do other tasks in between equipping so keep clicking until they are completely done and then they never get stuck in the loop again:
