Hello.
This can happen for a few different reasons, but most probably because of the cache:
Clear your browser cache: Sometimes changes made in WordPress don’t show up on your website because your browser is still showing you a cached version of the page. Try clearing your browser cache and refreshing the page to see if that helps.
Otherwise, please send the live URL of your site by the private area so that I will check it for you and assist you accordingly.
Best Regards
