[Graphic✓] unLZ Help! Palette of the custom sprite is imported, but not the actual sprite itself (Emerald)

[FoodBar]

I'm specifically trying to import a brand new sprite to replace one of the trainers.
I was able to successfully do this with Brendan and it worked perfectly! But after following the same steps to replace the sprite for Roxanne, it fell apart.
In unLZ, everything seems fine after importing my new sprite, but when I go back to that specific sprite, I can see that the palette for my new sprite is there, but it's over Roxanne and not my new custom sprite.
I've tried almost everything that I can think of, so I made an account here to post this in hopes that someone can help me!
I'll provide images of exactly what is going on, as my description might be hard to understand.
