Can't open Languages tab from the "Custom D&D 5e" Module

Hi all, I've been using Custom D&D 5e by Russell to make some edits to my game and for some reason I haven't been able to open the Edit Languages tab in the module settings window. I've been able to open every other setting, but just not the Languages one. Anyone know of any incompatibilities that the module has, or anything else that could be causing the issue? I'll put my currently active list right here:
