I figured it out.
It happened when we close the current note before signing.
Not to lose current note, either forward to myself or signing must be done. Otherwise, in case anyone(if forwarded to others) close the window, the note disappears.
Recovering note was not effective as erased blank note is saved.
I think it will take a while for me not to close window before signing.
I still have to print out draft progress note until I sign it in afraid of losing note.
Thank you so much for advices and suggestions.
