Columns Not Sorting - Numbers 3.5.3
I have a very simple spreadsheet that I made in an old version of Numbers, that I'm now trying to work on in Numbers 3.5.3
I have an "Emissions" column, full of figures (e.g. 139 g/km). However, when I try to Sort Ascending, or Sort Descending, the numbers don't come out in the right order. The Data Format of each cell in this column is set to Automatic.
Any idea why this isn't working properly? Seems like really simple stuff.
