Bug in the Timeline feature

Is anyone else seeing this bug in the Timeline feature in Articulate Rise?  It first appeared a week ago. I submitted a case but have not heard anything back. I submitted a case again today as the bug remains.

When I added an image to a Timeline the image appeared twice in the content box. Also, the audio file that was already added was duplicated. AND every other module in my Articulate RISE portal now has double image and audio files showing.
