Movies importing as Home Videos.

I have just upgraded my media centre computer from a MacMini 2010 to a new MacMini 2020. I tried importing my TV Shows into the new TV app but they are coming in as Home Videos and not Movies as it did in Mac OS 10.6. I have checked the Metadata in the files and they are all set as Movies and not Home Videos. I can change them manually in the TV up but there are lots and that would be cumbersome. Is there some way to fix this?
