Ah, I know what happened.
Police Trap #1-3 are not in the public domain. They were made by Simon & Kirby's 'Mainline' company before they were sold to Charton.
Mainline books are not safe for DCM. I've moved it to the Suspect area.
But if you were to go into Edit like you have for some others you can move books as well.
No need to upload it twice when moving a scan.
Take care,
