Your browser stores each web page you view in a 'cache' so that, if you return to that page again, it can be loaded instantly without needing to download it again. That's fine if the page doesn't change but can present problems with fast-changing pages (such as on AB). Your browser has clearly (and rather oddly) cached what you viewed on 10 October.
You've not stated which browser you're using, so I'll assume that it's Internet Explorer:
Go to Tools > Internet Options
If the 'General' tab isn't already selected, click on it to select it.
Under 'Browsing History', click on 'Settings'.
Under 'Check for newer versions of stored pages', select 'Every time I visit the webpage'.
Click 'OK'.
Under 'Browsing History', click on 'Delete'.
Put ticks alongside 'Temporary Internet Files' and 'History' (plus anything else you might want to get rid of).
Click 'Delete'.
Click 'OK'
Close Internet Explorer and then open it again.
