GR6 Input sources: How to deselect artist list

I am new to GR6 and am having a play around so perhaps a bit basic? When I first opened up I had a long list of sounds to select from. Today I clicked on 'Artists: Dana Ruth'. This confined my list to just what Dana was doing. I can exit Dana and click on other artists but the list is still confined to that artist. Is there a way of selecting 'No Artist'? The same thing happens on all the Sources by type. I tried resetting the Library but it still remains stuck on what I select.
