Titles appearing despite being turned off

Hi team, I've recently uploaded the Agency theme from your site library for our new website, however when I click to disable titles within new pages, this function does not work.

This is an example of a page right now in which the title is set to be disabled: https://www.onlinegroupsuccess.com/resources-for-facebook-group-admins/

Image which shows the back end of our dashboard to illustrate the problem is here: https://www.onlinegroupsuccess.com/wp-content/uploads/2020/08/Fullscreen-capture-8112020-101310-AM.jpg

Image of what the page looks like here (though you can also use the URL above to go directly to the page in question) https://www.onlinegroupsuccess.com/wp-content/uploads/2020/08/Fullscreen-capture-8112020-101313-AM.jpg

All other options within the disable elements option work, just not the content title. Any help would be appreciated.

Thanks :)
