Having issue with one show for some reason

For some reason the show 1923 always come up with S1:E1 to watch when I’ve watched all of season 1 and am caught up on the current season 2. It shows all episodes with checkmarks that indicates I’ve watched them but when a new episode is available it will not have a checkmark beside it but doesn’t come up as the next episode to watch. It’s the only show that does this. I’ve tried marking everything in watched and deleting the show from my list and re-adding it. Nothing works. Any suggestions or help would be appreciated.

Do you maybe have it scrobbling from several locations? For example local file/folder through Plex, Kodi and also added on Amazon, or Paramount+ in a watch list there?

No I only use Kodi.

You probably want to report this to the kodi addon developer. I have no issues marking 1923 as watched when I do it from the trakt app or website. I’ve been following this show.

Some addons have a “clear Trakt cache” or similar in their settings. Try that.
