From your screenshot, it seems your MSFS is recognized ( assuming you use MSFS and with "GSX" you mean "GSX Pro" ), that is assuming the Community folder I see there IS the correct one.
Assuming all of that, the only issue seems to be you must have clicked the MSFS logo when it said "Click here to HIDE products", so all products are now hidden, which can be seen since they now say "Products are Hidden".
