Playlist radio for "Liked From Radio" is inconsistent with my liked tracks

[MotoMind]

I added approximately 5 indie rock tracks to a Liked From Radio playlist consisting almost exclusively of black metal and death metal (~200 tracks), and now all I get is hipster rock. It appears to have seeded off the tracks I liked from the bands "Foals" or "St. Lucia". I do not get a single recommendation in the metal genre. Please help. I do not want to listen to Bombay Bicycle Club when my playlist asks for Bathory.
