Wait a minute, I was correct posting here I believe or maybe it should be in PM Plus support.
My issue exists only in PM Plus.
In PM Plus Organizer, Browse tab I can list my Structured Keywords in the left panel.
I am attaching a screen shot below.
Please note my parent keyword "Upgrades" which has a long list of subcategory project labels listed by year.
Some of the project labels have their own subcategories.
You will see that PM Plus sorts the project labels that have subcategories first even though that puts the years out of order with the rest of the projects.
The various projects that do not have subcategories are sorted properly by year but they are separate from the group with subcategories.
This is wacky and defeats my purpose in listing the projects by year.
Also note that in the Structured Keyword Panel PM Plus handles this situation perfectly.
I am attaching a screen shot of that as well.
All of the exact same projects are listed in order by year whether they have subcategories or not.
This inconsistency shows that PM Plus is mis-sorting the keywords in the Organizer feature.
Hopefully this inconsistency can be eliminated or at least provide an option or custom sort feature that resolves the issue.
Thanks
