The major items and the items under them are in reverse alphbetical order [Z-A].
Is this intentional?
Usually, if a list is ordered it is in alphbetical order [A-Z].
Click on the title bar within the dialog. A tiny arrow indicates the sort order. It’s up to you to sort any column the way you see fit.
BTW, this is a Windows standard, it works the same wherever you have set the view to “Details” (in Windows file explorer etc)
