Don't be confused with the naming of the levels. If you compare the level name and the position in the PB you see that it starts with the lowest level (named level 4 cause i didn't care about the names in the testproject ).
The sorting is actually what you want. And you can switch between ascending or descending for the sortings by hight (Associated Level).
If you want that value behind the name i don't have any cloue.
Thanks for taking the time to submit your idea. Unfortunately, this idea did not get the support of the community over the last 6 months and as such we will not be pursuing it at this time. Please feel free to rework (titles and clear descriptions are really important) and resubmit this one down the road.
