Two series being combined into one

Still learning (and learning quickly), but I have a new problem.

I have two folders that not only are the shows getting mixed in Plex, but the series image isn’t even remotely correct. The folders are named as the following

Challenge of the Super Friends (1978) {tvdb-76837}

Super Friends (1973) {tvdb-254222}

Despite making sure the folder names have the tvdb numbers, all of the episodes are being lumped into this one folder in the image below which shows a poster not corresponding to either series.

All files have the full name of the corresponding series in them, i.e. Challenge of the Super Friends S01E01 - The Demons of Exxor.mp4

Anyone have any thoughts on why this could be happening? Am I missing a step?

There was a discussion about this a few months ago that I was involved in. Because of the way TMDB uses external links for the TVDB episode ordering, it has gotten very complicated for these shows.

Read through this post, it may help you out.

Superfriends

… wow. Who knew 1970s cartoons could cause this many headaches?

Thanks for the info!
