Hi there
Here’s a breakdown.
My Aeon project was about 40 events, Story Arcs and Narrative Folders. I had placed half of them into Story Arc folders in narrative view. Some of those narrative folders had story arc sub folders which had events in as well.
When syncing with Scrivener only the first event had a summary in it. All the other events had no summary. A lot of events had no written summary as well just for clarity. I could not see any summaries in Outliner or Corkboard in Scriv.
I then stripped out all events from Story Arc folders and Narrative folders in Narrative view in and deleted all story arc elements. So in the end all I had were events and no arc or narrative folders. ALso no events had dates. I synced and then went back to Scrivener to see and all events still did not have summaries. Even the first event had lost its summary as well. I then moved all events to the trash. Then went back to Aeon to see if the events were still there in some way and they were. I then pulled the events from trash in Scrivener and synced again. Summaries still did not appear. Since I created back ups I went through this process a few times in slightly different ways and then for some reason summaries appeared in Scrivener. I lost track of how I did it I’m afraid.
