Hi there,
Welcome to SeaTheme forum.
It may be caused by caching. First, please check if your WordPress has any caching plugins installed. Disable the plugins or clear the cache before testing this page again. Second, please also check your hosting control panel as it often has caching settings. Disable them and then conduct the test.
If it doesn’t work, May I check your website? Because I need to check the live website, it is normally faster.
If you permit, please leave your wp-admin access (URL / username/password) to me.
Regards!
