tModLoader Armor sprite problem

[Ponczek123]

I created a sprite for a helmet, but instead of simply displaying on the head, the helmet sprite moves from the bottom to the top when moving. The sprites downloaded from Example Mod don't have this problem, and I don't know what the problem could be.

Your image is the wrong size. The head sprite sheet should be 40x1120, yours is 37 x 1024.
