Kwaj girl, your browser preferences are probably not set to load the latest version each time you load a page. You most likely are not receiving the latest version of the page but instead are loading an earlier version stored on your hard drive from a previous visit or perhaps an earlier version stored on your internet provider's local server.
Simply use the "Refresh" function for your type browser and that should load the latest version. To avoid having to do this each time, you would need to change your browser preferences and set it to check for newer versions with every visit to the page.
Here are a few previous FlyerTalk threads on your situation:
