Why does note expression data continue after the note is finished?

Hello. I am trying to learn note expression in cubase and I have a screenshot here which shows the current note expression.


I have vertical snapping selected because I only want semitone and whole tone pitchbending and it works so far but I have a problem when I play this back. The next notes are also affected by the pitchbend. Shouldn’t note expression data only apply to the selected note and not to the following notes? What am I doing wrong?
