I am still experiencing quite a large issue with the Wedding Stories pack

- Issues around editing a wedding event once it has been created. This has mostly been related to the Wedding Ceremony itself. Once the event has been created, it can only be edited once. After that, the edit button is greyed out and no further edits can be made. The only option is to delete the event and readd it. This doesn't always work though. Sometimes when recreated, it still cannot be edited. This obviously makes it pretty clunky when asking people to be apart of your wedding, editing outfits, adding a cake, etc. I have had to make sure I have done everything ahead of time, so the one edit I make includes any changes I need to make.
