My Expansions are not loading into Fraction. Plus

99% of the time it is about subfolders. Your "Expansions" folder needs to look like this.

2. Bottom left of the Plugin → Settings → Sample Path, and select the “Expansions” folder inside the Factory Content folder.

Restart the VST.

Important: The folder your locating must be exactly named “Expansions” for them to show up in the preset browser.

The "Expansions" folder is also where any of your new Expansions are going into like Monuments or Core-Synth. But make sure there are no subfolders otherwise it won't show up.
