overworld music plays in the otherisde

[Omega58]

Minecraft Version: 1.20.1 Mod Version: 1.2.1 Mod Loader: forge

Description: So I was playing creative mode and exploring the dimension, and then overworld music started playing. the only way to listen to the mod's music in creative mode is to use ./playsound deeperdarker:music.otherside (insert the biome name here as there's music for all 3 biomes).

To Reproduce: Steps to reproduce the behavior:

1. play in creative mode
2. go to the dimension
3. wait until music starts playing
4. See error

Screenshots: If applicable, add screenshots to help explain your problem.

Additional context: idk if it fits here, but i have the same problem with the undergarden so it could possibly be a vanilla or forge bug.
