Does your note only disappear from 10-pm to midnight?
If so, get an update (or use a previous edition).
I almost ditched Amazingcharts because of a glitch in programming that made forwarded progress notes disappear from 10pm to midnight. There's a whole thread on this.

If you have updated Amazingcharts, then this may be a new program glitch... which is why I will wait on getting my updates until there is a very good reason to do so.
