SG saying show does not exist on TheTVDB but it does

I’ve been having this issue for a long time now. Some of the shows I’m trying to add will not add to the app. It says that they do not exist on The TVDB but i checked and they do appear there. Is there a way to force the app to add them? Thanks

App use’s TMDB, not TVDB as far as I’m aware.
https://www.themoviedb.org

eg: - https://www.thetvdb.com/series/lambs-of-god
not showing here yet: - https://www.themoviedb.org/search?query=Lambs of God

@corkiejp SeriesGuide uses TheTVDB for shows. See https://seriesgui.de/help#sources for details.
