Can't create a radio station from artist

In the past few days I've noticed that when I try to create a radio station from an artist I have been having problems.

First, when I'm on an artist's page and click on the three dots, I don't always get an option to "start station." I have to click around on albums or songs and then back to the artist's page before I even get the option.

Then, when I finally do have the option, clicking it only gives me this message in the now playing area: "Unknown title" then I get nothing.

However, I CAN start a station from a song or an album.

Interestingly, I am able to start an artist's station on my iPone and then it appears in my "recents" list.

Any help or suggestions would be greatly appreciated.
