A simple 8 bar 4/4 track.
Note track mode. Piano role. Polyedit. Press 2nd and Delete.
Expected behaviour - All notes on the selected row on that page should be deleted.
Observed behaviour - All note on selected row are correctly delete, but so is the note on that row in the NEXT PAGE is deleted!
In monoedit mode the same thing happens.
This is quite a fundamental bug in a frequently used function.
