Unofficial Skyrim Special Edition Patch

My character is a female dark elf. I've had her wearing a circlet for a while but a few days ago it disappeared (within the last week from Sept 26). It's still on in the inventory, the enchanted effect is on under "active effects", but it doesn't show on the character. I wondered if it was this particular vanilla circlet that was being effected so I tried to equip another circlet. Instead of replacing the original circlet, they were both equipped. Neither showed on the character but both were enchanted and both of the enchanted effects showed under "active effects". I tried equipping a third circlet which the game let me do. I didn't have any more in my inventory so I'm not sure how many it would have let me equip. My follower dovahbit also had several helmets in his inventory that were equipped at the same time

I'm not positive but I think the circlet disappeared after the first quest in which you become a werewolf, after her first transformation.

I tried changing the order of the mods but nothing fixed it. I found an old post from at least a year ago about an issue with this mod and female elves. I tried disabling this mod and the head gear reappeared and only allowed one to be equipped at a time again.
