Bottom-right glitch in sprites. (Bug)

Hi, RiffyDiffy, here! So, I'm ripping some stuff from the Cuphead DLC, and trust me, I got this problem before (When trying to rip some cutscene sprites from Cookie Run: Kingdom.). See, the anteater's sprites has this weird glitch in the bottom-right corner, and I absolutely have no idea what is causing it. If you can provide a fix to this, that would make me happy. Thanks for reading this!
