After doing some looking up I found that you have to ask krin bc mine marks everything based on ID. My starter being the smallest number of 9097, is at the very top. and I inspected every pet id number after that, they are organized accordingly. Which is odd bc looking at the screen shot it looks organized, but there are at least a pair that are not organized. I have even tried searching through different categories, even going as far as doing all species with hatchling and adolescents included. Maybe its some sort of glitch on yours. IDK, I just know that what I see in the screenshot is not what I see in my generator menu.
