Rise 360 Edit view is not showing all material that preview sees. Cant make edits!!!

When I logged into articulate today and when into one of my courses to edit, alot of the sections are blank or missing information. When I select preview mode I can see everything, but it is gone when I choose to go back to edit.

I have attached screen shots of what is seen in both views.

I have a big deadline and need to make final edits for launch.  I need help asap!!!!!!!!
