There is a way. You have to put the cans inside manually now instead of having them snap into position. Not sure if it's a bug or an intentional change. Just pick up the can, rotate it to the cap is facing the inside of the refueler, and put it inside so it's mostly lined up with that rectangle it used to snap into. Don't need to fix it in place or anything. Doesn't have to be perfect, just has to be pointed the right direction.
