Champion Profiles in the Shop

Something that I have noticed is that the "overview" and "abilities" of the champions that you click on in the shop are not always complete. For example, it took a long time for Riot to update Kayn's stat circle (damage, toughness, mobility, etc). Now, the ability showcase of Akali haven't been updated yet. I don't know if Riot just forgets or it takes a while for them to update it for some reason.
