HELP! Project M ressetting to Brawl after a match!

[FalchoMex]

So i have this really, really weird bug/glitch that happens when i finished a match, the music just comeback to normal and the roster still the same (Roy and Mewtwo still there) but when i backout the menu is the same as Brawl with the same fonts the background and everything and i want to play a match again in FD but its the same FD as Brawl! and then crashes with a sound like "Eeeehhhhhhhhhhhhhhhhh". the funny thing though is that when i play singleplayer, it works perfectly (Without played any matches previously), without crashing, no errors etc. i was trying to find if someone had this problem too but no it seems that this is a unique problem. i was playing it with a disk but i bought i USB Flashed Drive put Brawl on USB Loader GX the Sd card Ocarina: On Hooktype: VBI it launches Project M perfectly, But the same problem ocurres.

HELP ME IF YOU HAD ANY IDEA OF WHATS GOING ON!
