Excel filter error

Filter doesn't work in my excel file for Column U and Column V.  I attach the excel.  For Column U and Column V, most cells are "#N/A", but you can see there are real data in some cells for example U161 and V161.  But when clicking the column filters in U3 and V3, you can only see "#N/A".  Can anyone explain why?  Thanks.

That's because columns K:M are completely blank and probably you selected the range A3:V3 and enabled filter. Since there are empty columns in between, there are two separate data sets columns A:J and N:V which are non consecutive data sets and as far as I am aware, you can have filters on one data set on the worksheet.

You either remove the blank columns or only apply filter to the range N3:V3 and the filter on columns U and V will work fine.
