Boards icon stuck on the same icon for months?

Ok, so I have a small problem. My boards icon has been the same for 9 months, regardless of the fact that I have changed my icon in-client for countless times. Now, I've had this creepy Draven icon on boards since April. No matter how many times I change it in-client and to what icon. It should be Elementalist Lux icon at the moment. Does anyone know how to fix this? I'm really creeped out because every time I log in to League website, I see Draven staring into my soul

If anyone knows how to fix this, please tell me. Thanks a lot, and sorry for my english if it's bad (not my first language)
