[gameplay] bug - most recent champion order

My match history shows what I've been playing, which most recently has been etc. I would expect then to see the same when I sort my champion list by Most Recently Played, but instead I see . Why the difference?

On a personal note, I'd love to be playing more and have been trying to formulate a theory as to why I haven't seen in ages! Is he on vacation? Or is the erroneous sort order related to the fact I never see him in ARAM, which is what I almost exclusively play? Is there a conspiracy?
