Issue with B2W2 Pokemon Sprite editing

[RetroNC]

Hello everyone, I've recently run into a wall in regards to editing sprites. After many hours of trying to fix it myself, I am now looking for any help. As you can see by the second example in the attachments, the Duncbat and many other modified sprites have worked successfully before when replacing them with new sprites. However, when I modify and replace Zubat (as shown in the example down below), the most it changes is completely being messed up colour wise and having no changes to the design itself. I use BWSE, I use the same palette for the whole pokemon (its sheets and sprites, then for the shiny - it has a matching palette for every sprite but with different colours compared to the regular), I have indexed colours and I have tried adding it as a sole change on a fresh narc. What could be the issue here? If you have any ideas or suggestions, please do let me know!

(I've also added the zubat's sprites and sheets into one zip as an attachment down below if it helps!)

Solved - Pokemon that have gender differences have a white outline square in the sheets to signify that the Pokemon (in this case Zubat) has two separate sheets for both genders! In this case, after I edited the Zubat with PKHex to be male, I found out I was only modifying the male version this whole time, while the version I had (female sheet) got only changed with the new, messy colors. If it had a bigger gender difference, I most likely would have noticed it earlier haha - hopefully this helps anyone with the same issue :)
