Not being directly helpful but I searched in Kodi where I have tmdb as the show provider and real debrid as my stream provider.
All episodes show but I don't see any links from torrentio, which my add-on uses.
Maybe the issue is the default show provider stremio uses, see if you can add another one, and torrentio.
€250 is a hard price point but a Samsung A series is probably going to give the best performance for the money.
