Sorry for the late answer...
When scanning TV Shows it scans the folder's and adds the images for the folders but never scans the files in the folders
when you go into the addons there is a typo on the TV Shows addon which is suspect is what's causing the problem
i think maybe people who have updated to this build instead of going straight to this build may not get this problem
See image atached
I have installed metadata.tvdb.com-3.3.0 and that is working fine (What i used on Kazaq 8.2.2.3)
This is not a LibreELEC specific issue, but there might be some confusion in the Kodi repo, I will try to find it and report it on GitHub to the Kodi devs.
Until then, you can access the latest version for Leia here: https://mirrors.kodi.tv/addons/leia/metadata.tvdb.com/
I dont know if you do requests but if you do can i request that the cec popup's are suppressed unless its an error
Whilst looking how i can disable it on every boot i ran into coreelec added a patch to suppress them unless there's an error so you could most prob see what they did
I would need a little more detailed information than that, because I don't know exactly what you mean by that.
