minecraft duplication glitch

So basically if you have a beacon in survival and play Minecraft on mobile when you switch to Minecraft pocket edition and make sure the stuff that is stackable are in your Hotbar you can duplicate them in a beacon you just need to press on it until it reaches 64

so from 1 to 2 to 4 to 8 to 16 to 32 to 64 in a matter of seconds, you will have 64 diamond block for example 

It works on realms and  servers and offline 

please fix this bug it is ruining the game than thank  you Minecraft team
