Lost Information When Editing Event

I’ve successfully created events and have been updating these events with new information and links that has since emerged. When I edit the event all of the “Event Data” is lost including the required fields. This means each time I edit the event I have to re-enter all of the event data include the address and schedule. For obvious reasons… this is tedious and I’d like to get it fixed.

My first thought is that file permissions somewhere need to be updated? Open to any ideas.
