collection -> champions -> "recently played" is completely broken

According to recently played the latest 3 champs I've played are Renekton, Kai'Sa, and Darius in that order.. The last time I played Renekton was actually Oct 27th, 46 PvP games ago (and probably 40 distinct champs ago). The last time I played Kai'Sa was SEPTEMBER 27th, which was OVER A HUNDRED games ago. Darius was in the middle, Oct 13th.

There seems to be no rhyme or reason to the champs in my recently played at this point. I don't have any filters on either... all champs, all roles.
