Items taken out of chests are deleting.

Platform: All
When a chest is constantly being /cloned to the same position by an active repeating command block, trying to take an item out of the target chest will 3/4ths of the time delete the item. This can be hard when you have a starter chest.
1/8ths of the time the item is deleted, it is delayed by 1-2s.
Affects dropped items too.
