@strwht , I had the same problem as you. What Infuse was doing was consolidating the UK and US versions of the show. This gave me more seasons of The Office than I was expecting as it added in Specials. This is due to how TMDB finds shows. TMDB will preference the most popular version, where TVDB uses first released as its reference. For example:
Folder (and file) naming when using TVDB
The Office - 3 seasons (2 + Specials)
The Office (US) - 9 seasons
Folder (and file) names required to work with TMDB
The Office (2001)
The Office (2005)
What Infuse was doing with the original naming structure was combining both the UK and US Season 1 together and also Season 2. And then adding the UK Specials as an additional season to the US show.
Other shows that were impacted were Life on Mars (US and UK) and Wallander (UK and Swedish).
Shows such as The Killing (Danish and US) and The Bridge (Swedish and UK) weren’t affected as I had retained the non-English names for these shows and TMDB had no issue with that.
Hope this helps.
FWIW, whilst Steve Carell was good, Ricky Gervais and the UK version are brilliant !
