I was suspicious before but now I have confirmed it: note tracker is getting some wrong hands for the default notes.
If an opponent 3bets vs. a steal his holdings will appear 3 times: "3bet range", "3bet Blind vs setals" AND "Called 2Bet from blinds range"
Of course the last one is just wrong and quite misguiding. I noticed many opponents with notes like "[P] Called 2Bet from blinds range{KK} (1)" which might lead to big mistakes. In fact, he never called with KK pre but 3bet with it, but the default call 2bet note is getting that hand as well for some reason.
