Help with multiclassing and mods

[RevanFanMan]

I'm having an issue. I'm using the wizard unleashed mod, the sorcerer unleashed mod, and the level 20 multiclass mod. My issue is I can't get my character to level 20 despite having the mod. I followed the instructions and multiclassed my sorcerer into a wizard at level 10, and made sure to install the multiclass version of the Unleashed mods. It worked like a charm on the other characters for different classes. But when I try to multiclass a sorcerer to a wizard, it doesn't work. I'm not sure which mod is the cause, nor what the solution could be. It's these mods in question:
Wizard Unleashed: https://www.nexusmods.com/baldursgate3/mods/710?
Sorcerer Unleashed: https://www.nexusmods.com/baldursgate3/mods/650?
Level 20 Multiclassing: https://www.nexusmods.com/baldursgate3/mods/570?

Could someone help me please? I'm at a loss on what to do. I'd really appreciate any help. Thanks for reading this and I hope you have a good day.
