That definitely sounds like a bug. I'll try to reproduce the error by copying what you've listed above.

I have an update:  I just finished adding several new songs to that collection.  After doing so, one of the new songs was missing; this turned out to be my fault, for not noticing that it has the same filename and title as an existing song which isn't part of that collection (and isn't supposed to be).

...but before I realized that, I went into the collections editor.  There I found a recurrence of an old bug which had been solved a long time ago, but which seems to have come back:  when article sort is in effect, deleting a song from a collection sometimes deletes the wrong song (i.e., the song I selected to be removed was still present in the collection after the deletion occurred, but the song just above it was deleted instead).  Since there's no way to back out of a collection change, this is kind of nasty. :-(

Meanwhile, after I left the editor, the collection was sorted correctly again!  I don't pretend to understand this.


[ update:  I just found the thread in which the collections editor problem was originally reported:  http://zubersoft.com/mobilesheets/forum/...81#pid3181 ]
