Chromecast: Is this supposed to happen?

Today while I was trying to play music on my Chromecast, I noticed that there were two options for each of them. I tried one of them and it didn't work. It gave me a blue screen that I've never seen before and then proceeded to tell me that my music could not be played. I tried the other option for the same Chromecast and it worked just as it usually does.

I proceeded to go to the quick settings in the notification bar. Another tile filled in. It said "cast screen" with a little Chromecast symbol. I tried to cast my screen to the TV but it gave me an error and never worked.

Is this added functionality for an update or is something just going wrong? Has anyone else encountered this?
