some characters pngs are cut off

[GuyOnAComputer]

for some reason, when some characters' pngs and xml are input, it will output cut off pngs. this isn't what the actual in-game sprites look like, so something is happening incorrectly with the program

here is the png and xml of the character it does this on: https://www.mediafire.com/file/6dcnpkspn5ihh15/pulp.zip/file

The XML seems to have positive frameX and frameY values, something that typically ISN'T supposed to happen. It might have something to do with how the XML was made in the first place. This program typically works with all PNG/XML combos I've worked with, and all of their frameX and frameY values are negative.
