I am using Excel 16.31 on OSX 15.1 Catalina
I have a spreadsheet which isn't filtering as I expect. I use filtering on a lot of other spreadsheets, and they work fine, it's just this one.
When I go to filter the sheet, all I get as filters is the first line in the spreadsheet, and nothing beyond that.
I have attached the spreadsheet here in the hope somebody can find the problem for me.
thanks in advance
