John,
That is very odd. I have never encountered that problem. At first, I was thinking the chart was being forwarded to one database and then being brought up from another except you say you can "finish" the note. It may be a bug, but I would make sure every Amazing Charts is using the same database.
It would be helpful to see some print screen shots. You can send them to my email address in my profile if you don't figure it out. Or give more details. Good luck.
