Running the following report select cardnumber, firstname, surname, categorycode from borrowers where categorycode = <<in "s">> returns no results. Inspecting 'Show SQL' reveals select cardnumber, firstname, surname, categorycode from borrowers where categorycode = NULL however where categorycode = <<in s>> and where categorycode = <<"s">> both work.
It seems to have been fixed, works for me. Can you confirm?
Confirmed.
