Slimefun glitched barrel

[DShifter]

Spend 7 hours straight today making 9 "Deep Storage" Barrels. and they turn out to be glitched. I've noticed that in the Lore of the item, it says 1048576 stacks of space. But apparently, on all the forums and description of Slimefun plugin I can find on google. The correct number for deep storage unit should be 16384, and that number is 1048576/64. That's the first glitch. Secondly, whenever I put any item inside the barrel. The barrel eats up the item I put in there, rather than storing it. One last thing I noticed was how whatever amount I put into the barrel, the "amount of blocks" int the barrel will change accordingly to the number of items I put into the barrel at once. Would appreciate it if someone can look into the code.
