members' traceability

In the path, Community > Members, if someone filters "Super Members", the members with amount of points >=1500pt doesnot appear.
In other words, Super Members with >=1500pt and <2000pt, seem to have been unrelated to the element "Super Member" of the filter: Role.

I am reporting this, mostly due to my personal nerdiness on such things... It is for sure something trivia or secondary...
