Commented Unassigned: Cannot set multiple filters [9335]

sheet.RangeUsed().SetAutoFilter().Column(1).AddFilter<string>("testfilter1");
sheet.RangeUsed().SetAutoFilter().Column(2).AddFilter<string>("testfilter2");

Both filters are visible on the dropdown, but only last filter takes effect on the rows.
Comments: As far as I know Excel's autofilter only works with one column at a time.
