a lot of names, same textures

[Gumiho]

I've been trying to create a new texture pack for Dragon Ball Z: Tenkaichi Tag Team as the only one I could find was very incomplete (this one), I did make some textures (another example) using Hanz0's pack as a basis, but for some reason, the textures I modified (and were not already modified in the initial pack) doesn't work all the time

just started the game
one match later

I can activate "save new textures", but all that does is save the textures that doesn't work again, then I have to get the original images duplicate them and rename to the name of the duplicates, but this just keeps happening and I already have like 3 or 4 instances of the same textures in some cases, If anyone knows how to solve this please tell me how, I already watched/read a lot of guides but I still don't know what I'm doing wrong

the texture pack in case anyone wants to test it out our something
