Cant see columns when adding a State group in the Music Track Property Editor

Question

I have a Switch music track with 2 tracks that i want to crossfade depending on a State change. When i add the State group into the States tab in the Music track property editor the only column i can see is "Change occurs at" and so i cant specify different volumes for each one of the states on the State group. I checked the "cxonfigure colums" and they are all ticked so i really dont know what might be happening.

Any ideas please?

Thx
