Only Murders in the Building, [TV] Use Custom season Folder Name Format, TV Show does not use the library default for AutomaticFolder creation (Season {Season:2}), it uses customFolderFormat Season {Season}
This means that the library default is to call seasons 'Season 01', but the selected show has its configuration set to deviate from that and to call seasons 'Season 1'
Only Murders in the Building, [TV] Use Custom season subfolder Format, TV Show does not use the library default (libraryDefaultFolderFormat) for folders creation, it uses Subfolders per season Season {Season} (customFolderFormat)
Same as above
Only Murders in the Building, [TV] Use default source provider, TV Show does not use the library default, (The TVDB), it uses The TVDB (Hardcoded)
Shows can be set to either customise their source or use the default. In this case the show in quesiton has been linked to TVDB. The default is also TVDB, but the show is fixed to TVDB. If you were to change the library defualt from TVDB to TMDB then the show would remain linked to TVDB (despite you posisbly expecting for it to move across)
