Models - Sort by...

[Gemini]

Can somebody explain to me how they are sorted girls in the tab "Models"? We are there to choose from three options:
Most popular, Alphabetically, Rating.
On what basis does each of them?

Most popular - whether it is the number of downloads of movies (purchased movies)? If so, whether the total number of downloads for all the movies with that girl. Eg. If the girl who starred in two scenes, and each of these scenes has been downloaded 100 times (a total of 200 times), it will be ranked higher than a girl who appeared in one film, and the number of downloads for this scene was 199?

Alphabetically - in theory, this ranking is understandable. Girls should be arranged alphabetically. Except that it does not work. After clicking "Alphabetically" girls are not arranged alphabetically.

Rating - Here, too, do not really know what criteria should be ranked girl. But I see that they have been arranged alphabetically! Why?

And why we can choose from "Female", "Gay", "Trans", and when we click "Male" shows a blank page?
