Bugs in All stars (Mario's Madness)

Hello, I have many bugs in the song All stars from the Mario's Madnees mod

1. In the first act Mario does not appear (the song remains normal but you can simply see how he sings into nothingness)

   1. In the second act neither Yoshi with his pipe nor Wario's pipe appears (Wario does appear)
      
   2. In the final act Bf's memories do not appear when he is singing I have already reinstalled the mod 2 times in the most recent version and nothing, the song can be finished but it is a bit shabby, all the rest of the mod works well and no bugs occur, would anyone know how to solve this?
