Dynamic background bug?

My background is fixed on Ivern, who was at ONE point my most played in the last 20 matches, but as you can see, is not even on my last 20 match history any more. It should be lulu or kindred, but it's fixated on ivern. I've tried changing icons and nothing gives. Even an interactive icon like from my ultimate sona skin thing. It just always goes back to ivern. I love ivern as much as the next guy (and i want to play him more but i was testing to see what was going on with my background) but i want my background to be lulu/kindred.... to reflect my last 20 played.

edit: It fixed itself after the client update with the "your shop" fix. It's now lulu. However, if it does it again i'll let you know.
