PokeDSPicPlatinum Sprite issue

[Daimonwng0]

Hello it took me a while to figure out how to use the program correctly, but in one of my attempts to change a pokemons sprite the result ended up looking different than my original png; it was slightly distorted. For clarification im attempting to replace one of the less used pokemon with Zoroark and its pre-evolved form, but the sprite im using gets distorted after inserting it. Any tips for how to fix this?

it probably has too many colors, there is a 16 color limit, and the first one must be the transparency.

Thats probably my issue then, I think it had like 24 colors in it so they just got cut out.

Thanks for the help!
