Front Row issues: TV programmes showing up under Movies and nothing showing up under TV shows

Earlier today my TV programmes from iTunes would show up in Front Row under TV shows and would be sorted by episode number, but I did something weird and now Front Row TV Shows menu just shows "Front Row cannot find any TV shows." And all the TV programmes show up in Movies in Front Row instead and are sorted alphabetically

iTunes correctly shows them as TV Programmes

Here's all the metadata that's filled in: Name: (name of each episode) Album: (name of TV programme) Year: (year) Track number: (ep number) of (total number of episodes) Genre: (genre) Programme: (name of TV programme) Episode number: (episode number) Media Kind: TV Programme

OS X 10.6.8 iTunes 11.4 (18) Front Row SW Version 2.2.1 (314)

Any ideas? It was working earlier
