Music mod recurring issue - Potential bug

[aaaaaaaaaaauaaa]

I made a music mod that plays a random set of music for each sound event. When I add all replacements except summer, everything works fine.

When I add summer music, winter music plays cave_danger music instead of winter music. When I continue to play winter, the music eventually breaks and plays really loud static.

I've double checked EVERYTHING and everything looks right. I even remade the full mod from scratch and this issue still happens, so I think it has to do with the game instead of my mod.

Does anyone know what could cause this issue?

I attached my fmod project file and the music script.
