I never thought to use the delete bars function; I did it old school: went to where I wanted it to stop, set the from now point, went to the bar limit, set the to now point, selected all tracks, did a cut with the close hole option. If that didn't work, I started examining each track in note/staff view where the song should end to see if I had anything like a series of tied whole notes. If I did find these I would use the edit-note mode to check/edit their duration.
