@PookieBelle00 There is a possible fix. Rebuild your database. Or else do what I did,
-Remove USB external storage if you have it. (Settings->Devices->USB Storage Devices-> select your USB Harddrive, it will have a green dot showing what is connected->Stop Using This Extended Storage.
-Turn Power off (hold PS button, power -> turn off console)
-Physically unplug the console from the power supply at the back of the hardware & not the wall outlet
-Set a time for at least a minute I left mine unplugged 5 minutes.
-Plug your power cord back into your console hardware.
-Turn the console back on.
The content should now be visible as owned & begin to download. If not reuild your database.
