I have noticed if you try and sort by the Track files by clicking the Track field tab it will only sort accending/descending order if the numbers are integers. So for example, I have 16 tracks on CD2 rip. They are numbered 2.01 to 2.16. They will not sort. So I have changed them all to 201 to 216 and not they sort.
Is there some function I need to enable?
