Editing the "Add Dynamic Difficulty" function?

I tried using this and the lowest dynamic difficulty will have like 4 chords show up in an entire song which is so low that there's no chance for the player to ever level up and they just stare blankly as the song plays and no notes show up. Is there any way to edit how it adds dynamic difficulty so theres more notes at the lower difficulty. I feel it should match up more with how the base game tracks are.
