Problem finding end of a tick

Hi guys my problem is that my plugin sometimes doesnt correctly find end of selected notes but other times is correct

As picure show I selected first measure only and it should paste notes with same rythm but diferent pitch right after first measure but it starts on third.

Do you guys see the problem in the code ? Sometimes when I select notes it works properly but other times not. Thanks
