Annotation arrow won't go away

[LA10]

When my participants use the annotation away, it stays on every slide and I cannot erase it.  I have to stop sharing and start sharing all over again to get the arrows to disappear.

I also am seeing this. Appears to be a bug with the Annotate tools ability to delete arrows.

This has happened to me at as well! When I am host as well as a attendee.
