Custom sounds not working, and console spam

[JerryHan3]

I tried import a NBS song that use custom Minecraft sounds, other than noteblock sounds, but those custom sounds don't play, and the console is spammed with the following warnings:

Is this related to NoteBlockAPI? Or a naming issue with NoteBlockStudio software?

One of the custom instruments in the song has Custom/entity.experience_orb.pickup as the path to the sound file. You need to open OpenNoteBlockStudio and change it to entity.experience_orb.pickup in order to play it properly.
