Haii >w<, there is an issue where the filtering system in the +Filters dropdowns is basically broken. 

I've looked on most filtering options in the component gui, and all of them are empty execpt: Device types, Footprint, Manufacturer, JLCPCB Part Class, Supplier Footprint, and Value. Also, going into +Filters just shows all of them avalible regardless what it is on, but it does show the relevent ones for the FPCs at the top. I have a screenshot of what im seeing here on the FPCs "Pin Number" Filter (the "FPC, FPC (Flat Flexiable Connector Assembiles" to be exact). :3

The blank dropdowns:

+Filter showing everything (i scrolled down a bit to show the others):
