The issue was with the building of the query checking for != '' instead of !== null, as blanks are permitted. This caused it to place an empty AND inside of the query. Function reduceSqlFormula in plugin.class.php.

Not agreeing with the patch, as it gives wrong results, allowing selection of the empty row generating '' and wrong results.

Enclosed another patch, which gives expected behavior.
