Thanks ! I have not double checked yet. In db browser for sqlite, i opened the app.db file which i copied from the ps4. i set them all to one. It should be: if the value is " zero " in the can remove column then the game cannot be removed, if set to " one " then the game can be removed.
All i did was just checked on the ps4 in the options menu and the delete option is gone again, after i had set the values to one. also the ps4 is reporting the wrong size for the games, games which should be 40 gig is being reported as 150 gig, so i'm suspecting that there may be something wrong with the ps4, a deeper issue with something else other than the database problem.
