How can I access past splits and promotionals on lolesports.com?

Not really sure where else to post this but...since the beginning of the mid-season invitational, I've been unable to access past splits on lolesports.com. There used to be a dropdown on any page allowing you to change view into past splits. I write about League for redbull.com and often used this feature to fact check stories and make sure I was remembering matches correctly. Now I'm a bit confused where (if anywhere) I can go to find these pages. The page I've linked for example is the WFX/TDK summer promotional match, and as far as I can tell, there is no current way to navigate to that page from any link on lolesports. You'd need the url to access the page. Can someone help me out or point me toward someone who can?
