rebooting solved the problem

These are the ones that I keep trying to delete. Not stock craft. They are crafts that I have either downloaded and place into the saves/(save file)/ships/SPH folder, or that I have made myself and saved in-game.

No, these aren't the [Stock] crafts, these are ones that either I made and saved, or downloaded from elsewhere and put into my ships/SPH folder

Whenever I start my sandbox save, I go to my SPH and click open, and I see a bunch of planes. I don't want these planes, so I use the "delete" button in the "open" panel of the SPH. It doesn't work. So I go into the saves/[save]/ships/SPH and just delete them. They disappear if I delete them with the game running. However, as soon as I reopen the save, these ships somehow find a way to return from the great beyond right back to the saves/[save]/ships/SPH folder. How do I delete these .craft files so that they won't keep returning? And no, these are not [stock] crafts that I'm talking about. They are in /saves/(save file)/ships/SPH, not the [Stock] craft folder. These are not stock .craft files. These are crafts that I have either downloaded and place into the saves/(save file)/ships/SPH folder, or that I have made myself and saved in-game. Not Stock craft. Also, Steam Cloud is disabled.
