I am having a strange new issue. I'll cut to the chase. Because of the issue, I used Remove From Library. And now I cannot get that TV show to ever show up in the library after that, even after an new SD card with a new LE install in it. Where in Kodi do you reverse the "Remove From Library" status? That's just one problem.
My library is on a samba share on a NAS.
The second issue: some TV show's labeling is totally screwed up when you find them. Sometimes the season or episode is wrong, sometimes the title of the episode is wrong, or any combination of those. After straitening several existing shows out, and adding missing episodes, the newest episodes sometimes refuse to show up in the library. I can see them in the FILES area but not in the library. The content of the TV Show is set to TV Show/Local (should not be using an external database). While trying to solve this issue I ran into the OP issue.
