Popcorn bug - it's not possible to refill the popcorn

[Kuantum ♥]

Unfortunately, 5/20 popcorn is not enough to fill up a popcorn box, but it is also not possible to refill with a new full popcorn box. I can't serve customers because I can't refill it

It has to empty before you can refil it.
If it is showing 5/20, that is 5 servings of popcorn. Serve the 5 you have first,

Best thing to do get an employee to do the popcorn for you and make sure he is at level 2 so the refill will also be done for you.

Not a bug, just the way the game is set right now.
