Synopsis in Corkboard Card Not Saved

I write with my window split between the manuscript and the corkboard with my chapter synopses side-by-side. I rearranged one chapter and cut and paste some of the synopsis from one chapter into the new card. I then clicked File->Save and closed Scrivener. When I opened it back up, the synopsis for the new chapter was missing. I believe the corkboard card was the last thing to have focus before saving and exiting. Let me know if you need any more information. Thank you.
