Plex is taking personal videos and making them TV series

Built a new Plex server on a Qnap NAS and didn’t try to copy the metadata over from the old Windows server. But while I’ve set up a directory structure for each type (share/plex_media/movies, share/plex_media/home videos, /share/plex_media/TV) etc, the old home videos are now coming in as season 1 or 2 or 3 of some TV show (even though in home video directory) and bundled into 5 - 10 video “seasons”. Their data shows the path and I’m actually OK with just the fiel name as a title and a picture from teh video (as was done on Windows). There are 55 of them that are showing up in the wrong catagory (TV) and as a series. How can I unbundle them back into “Home Videos”? Actually, it’s also doing it to Movies, calling two unrelated movies episodes in a TV show. Help?
