When i place an emarald on the terminal it shows 2 emarald while i have 1

Do you have sophisticated storage and are you using double chests (from that mod)?

i use reinforced chest

Do they have double chests? If you're using double chests, try stacking them next to each other as single chests by shift-placing.

no i fixed the bug -> I connected the chests with cables etc but in reality you just have to put a terminal on a chest and if the other chests are stuck the terminal manages to take all the others and this time on the other hand the objects are not displayed in duplicate
