What merge behavior did you select? If you selected the behavior to use whichever setlist was modified last, it's possible the setlist on the phone has a last modified timestamp that is later than the tablet, so it's effectively being ignored. If you select the merge behavior to always use the changes from the tablet while synchronizing to the phone, then it definitely should have forced the setlist on the phone to match the tablet.
