Riddle me this, a sprite malfunction

I used FF3usME to swap in a couple of sprites, most of them worked out fine with no problems I have two others though (loaded on Edgar and Cyan) that seem to enjoy changing color in battle, depending on what slot they sit in.

First slot, the effected pixels turn a blueish grey. 2nd slot I get yellow/green. The third slot lets them turn a light brownish, and the bottom slot? Some kinda neon green...

Now, only those two have this issue, only in battle, and only a few pixels, not like a whole palette swap. When I imported them with FF3usME I didn't import either palette, I changed the sprite to fit the palette already in use and JUST changed the sprite.

Anybody ran into this before and remember how you fixed it?
