I have an odd problem on a tracker spreadsheet i use. All the columns have a filter, but when you click on the filter arrow it doesnt show you a breakdown of all the text values for that column. All it shows is the usual 'sort A to Z/Z to A', but the bottom half of the pop-up screen is blank, where normally you have a list of text values that you can further filter by putting a tick next to each.
It only displays (Select All) which you can tick, but its pointless as the column has selected all text values and hasnt been further filtered, which is what i need to do.
Does anyone have any suggestions?
