Lose Games after updating images

[Denodan]

How come when I update the database of a game that has a blank screen the game no longer shows up? Example Darius for Supergraphix has no 3D box, etc showing its blank. Goto the edit feature to add and download the media, download it, and then go to apply it, when I go back to the games its not listed but gone?

Just figured it out, unchecked all hidden games
