Site Basics Title Doesn’t update

The process to update the prefix of the title is very simple, but when you need to do a revision, the plugin doesn’t update the Site Basics prefix. I have modified and saved.. I have Yoast Test plugin and have cleared three SEO features as defined by customer service. I have cleared my cache before and after clearing the Yoast SEO feature buttons.

Totally lost and I still have my old prefix on my page.

Customer service has logged on, but no one has replied.

I have rebuilt my SEO three times with my new Site Basics but still the old one is shown.

I’ve searched my phpMyAdmin DB and I can’t find where it’s located via a keyword.

The page I need help with: [log in to see the link]
