Internet Radio not playing selected station

Hello community. I'm experiencing this problem with the Internet Radio in Itunes.

Let's say I select station "Solo Piano" within the Classical category, and the player plays any other station within the category.

It happens with any station in any category. I'm not sure this is the default behavior if the selected station is not available or if it's a bug.

I'm on MacBook Pro Mid 2012 - Mavericks 10.10.2.

iTunes version is 12.1.0.50
