As described by the title and illustrated in the screenshot, the portraits and with them the ability to view individual statistics is missing.
This first occurred about 2 weeks ago and hasn't changed back since, even with the most recent patch. I have not yet reinstalled the game.
The problem seems to resolve itself if you switch back and forth between pages, but upon first viewing of the page, the champions will be displayed for a fraction of a section before disappearing.
