It should not do this, the check boxes should save in a cookie. If you have disabled cookies this would be an issue. We also have some old links (specifically from google) or maybe if you have a page bookmarked, that link to URLs in the form of /lineup-cruncher/fanduel/NBA/ . While this will show todays data, it will not save the info in the cookie correctly since each days data is different. If the URL looks like this: /lineup-cruncher/fanduel/NBA/2015-01-09 (note the date at the end) then it should have no problem. Hope this helps.
