Main hand slot #3 showing locked after purchase

Main hand slot #3 shows locked symbol after purchase. the weapon in the slot can be unslotted and reslotted to fix the glitch, however once reopening inventory must perform this again. This also is present when viewing a merchant’s inventory, the item in main hand #3 is unavailable.

Same bug like photo. Both my 3rd slots actually open, even there are weapons, but at Vendors and at Chests, its not showing 3rd slots . Looks LOCKED.

Also BODY Armor should be top right, its going bottom left (changing slots with pants slot) you can see that at photo too.

Fix please
