This only happens to me on Windows and not Android, but sometimes when I open up Mobilesheets my songlist disappears and I get a big screen of the sorting alphabet. I can't figure out what button I hit to bring that up and I can never figure out how to get rid of it. What am I hitting?

Clicking on a header of a group (the "A" above all the songs that start with "A", for example) switches to that. Clicking a letter jumps to that section. It's a built-in behavior for the UWP component that I'm using.
