Try to delete the report from menusuite, recompile, see if it returns anything then.
If you still have one result then check what settings you need on the report like application area or something else. Compare with a standard report.
Otherwise recreate manually the report on different is with diff name. Then copy contents from old report, see how that one appears. If it works delete the old report, perhaps it's a metadata issue.
Cheers,
