look the default player texture updates are a nightmare and i only have so much time i can devote to this project, both slim and wide versions of all skins will eventually be supported, but for now if the slight glitches bother you, just remove the bugged textures
i also believe these currently do not appear ingame in 1.19.2? so this may not even affect anything yet until 1.19.3 is supported by this texturepack
