Two TV Series with same name but different years - cannot get both to show in Plex

The folder structure looks correct: It is basically “TV-Shows/Shogun (1980)” and “TV-Shows/Shogun (2024)”. Then I have the file names setup as “Shogun (1980) {tvdb-80284} S01E01” (same for the other series). I added the {tvdb-xxxx} later trying to solve this - but it doesn’t help.
I’m not sure what the Plex Dance is. I’ll check on that now.
Thanks
