Gecko os wont load anything on pikezers brawlex pack, it just goes to normal brawl, i have hook type AxNextframe on and sd cheats on but itll only load normal brawl. Is there any options to configure that im missing?

Okay so i have homebrew on my wii and other hacks for brawl seem to work fine, but i tried using gecko os and project m to load brawlex packs but none of the packs seem to work. Every time i run it through gecko os using hook type axnextframe it just comes out as regular brawl or the character selection screen is empty, i googled everywhere and couldnt find a solution, can anyone help me with this please?
