Whats with the inconsistency in champ pages

I just noticed while flipping through the champ pages of the lol website that a lot of champs aren't presented the same as others are particularly the newer ones. You know how the page showcases the champs rivals and friends? Well I noticed certain champs don't have their allegiances, rivals or full lore on their page. Why is this, I like that page helps me understand where everyone stands in universe with their peers even when it isn't stated directly and since the lore has been retconed its really the only way to keep up with the champs alliances albeit in a rather shallow manner.
