My Chest full with minecart 2556-01-10_15.15.14.png

When i remove some it come more 2556-01-10_15.15.38.png

Update:I hit the minecart and the minecart doesn't go in hopper and cause unlimited minecart but when i collect minecart on hopper it stop

Note: when 2 minecart is on hopper will cause this 1 minecart don't cause this
