Bracelet is worn and disappears at the end (Dead by Daylight)

Welcome, the game has a bug. First bug: when you take any object and go to the match, it fits over the hand like a bracelet, could not use it and in the end he disappears. Second bug: when you get the crystal on the higher rank hit the improved and automatically increases the level of survivor or maniac (I lost a very important perk for me). I hope for your help.
