Troubleshooting Style Issues with Nested Toggles in Divi Builder

I’m trying to insert a toggle within another toggle (nested Toggles), but I’m unable to modify the styles of any of those toggles. The plugin works, and the toggles’ styles actually look fine while on the Divi Builder (as if the styles actually worked and changed accordingly). However, after saving and checking it outside the Divi Builder, the styles don’t seem to work.

My Divi is Version: 4.24.2
My WordPress is Version 6.4.3

You can see my trial example on the bottom. The title of the Item is Level 0.
