Duplication ítems with Beacon

Hello, I would like you to solve a very annoying error regarding duplication of objects, in the minecraft bedrock edition, in the "pocket" design if you use a beacon (just give it and open your inventory and the beacon) and Press repeatedly On A stackable item, be it 16 or 64 the one in your inventory, can be multiplied until you reach that figure (either 16 or 64) is too annoying since it breaks the game, in my case my technical world because the player is be tempted to do so.
