Sorting by Diameter (mm)

Hi All,

In the Wire Style Manager I use the Diameter (mm) column to sort a list of wires. However I can't seem to make sense of how the software is performing the sort. Can anyone help make sense of the result? Is it sorting by just the first character? If so why are 10, 12 and 14 not with 1, 1.5 etc?
