Thank you. I understood what you said about. But let me show the problem in pictures
This picture is from replayer. And you can see that NoteTracker works properly. We have 10 notes for our opponent.
This is the printscreen of the same hand. As you can see NoteTracker icon looks like there is no any notes for the opponent. It isn't outlined yellow. And when I click on it or move mouse above there is no any notes again.
4.3k hands - there is no number of hands of my one session. For example, I saw notes for my opponent in replayer yesterday, but today I don't see any notes for that opponent while playing session
