Sorting disrupts filtered results

I have a numeric field, and have searched for all results that have no result in that field (*blank to -1). It displays the results correctly with only blank results shown. then when I attempt to sort them via date, it adds in data that has values in this field.
Previously this was not an issue. Has only started happening recently.
