Our site has 2 different series under the same name - Doctor Who. When it heppens system let you know it giving two results for one title like here:
Our TV announce just skip all such uncertain cases to give you only proven results. Maybe it is not very convenient but i could not make it better sorry.
Today NRK Super had "Ronja Rövardotter", but as a TV series, it doesn't get listed and not even highlighted (a link you can click to get info for it) when I pick full schedule. Same problem?
