I'm very new here. I've tried to figure things out from the Overview features, the tutorials, the forum and the Help feature. It's taken several hours, but I've figured out how to override input styles, and how to remove a column of ghost notes (unintentionally created as I deleted rows). I now have a beautiful document.

I tried a few style changes that selected multiple rows. Now, I have a few lines of "multiple selection" with no way to know what is in each multiple. Also, level 2 is selected and I can't unselect it.

I closed my outline and reopened it. Now, it has many fewer rows; what happened? And level 2 is no longer selected.

Thanks for your attention.
