Bug where i get hero weapons i already have

this is just a short clip of what i see after every battle, I do have all these already and there are MANY more that it tries to give me even though i already have them(the file was just too big to try and record and upload them all). it doesn’t hurt or make me lose stuff on the game its just annoying

NEVER MIND GUYS AFTER HAVING TO REFRESH A FEW TIMES IT SEEMED TO FIX ITSELF.
i dont know if the refreshes fixed it or if it was a short term bug.
