How are "Singles & EPs in my library" sorted?

In the Artist overview, does anyone know how the albums in “Singles & EPs in my library” are sorted? I can’t figure it out. Thanks

Looks to be by release date?

Thanks, I thought that too but I don’t think it works for the albums I posted

Is it popularity do you think? Thats the only one that would not have any order to it in terms of dates and names I think but I am not sure
