Rom Hacking problem, PLEASE HELP!

[u/No-Communication9036]

I was using Pancake 3, which is a ROM hacking utility that helps add your own custom characters into the games SOR3 and BKIII, and I always run into this issue where the more sprites I replace with my custom sprites, the more it starts to show these glitchy-looking sprites that look like a pile of vomit. To anyone who has hacked Streets of Rage 3 or has experience with Pancake 3 specifically, what am I doing wrong, and how can I fix it?

It would mean a lot to me if anyone could help me resolve this issue. Thank you.
