Where are the other Alt Universes on the Universe page?

So basically, when you enter the Universe page of LoL, if you select "Alt Universes", there's only Oddysey, K/DA and SG. That's a bit bs considering there are a ton of other skinlines that have good lore (BM, Project etc). I would really like to have everything organised in one place; it feels rather shitty to keep track of all the Alt Universes lore when you can't really sort it in any way.
