Loot Tables Filling Multiple Chest Slots per Roll

Hi in my mod I am attempting to make chests with loot tables. My only problem is that for singular rolls of the loot table the item is put in the chest but the amount is spread between multiple slots. For example, if I create a loot table that does one roll that has a 100% chance of putting 10 stone in, instead of one slot having 10 stone I get a random amount of stacks of stone which sum to 10 stone. Is there a way to fix this or is this intended? Thanks!
