Some scripture highlights not displaying

Today some of my online scripture notes and highlights at the end of chapters are not displaying on my computer. I know this because I make a notation on the last word of every chapter. Today many of these highlights/notations are missing. I saw this happen once before and I thought I had lost data, but then it resolved itself a few days later. Has anyone else seen this?

I noticed yesterday that the highlights/notes that had been missing are now displaying properly.
