This is probably because you have not cleared your store's cache.
Any changes you make to your store are cached until you manually clear the cache. If your store has cached any data, you will see Page cache: Update now in red at the top of the administration area. Click on the warning to clear cache. You will need to do this after every change unless you alter the cache settings.
You can disable the cache by clicking on Settings and then Page cache. You can disable it completely or set it up for specific pages.
