Did you figure it out? I'm having a similar issue where only the ALL folder appears. Used to have a lot.
Having strange issues just about with everything in the divinity engine at the moment. Effect editor wouldn't let me save or build a new effect until reloading the editor and file in question. Root templates GUIDs are missing from newly created roots for skillbooks, not allowing me to link the skillbook to the object stats. All sorts of trouble.
