Here is a page that has this problem:
https://www.torontowindowsanddoorsexperts.ca/about-us/

The page’s name is "ABOUT US" , but it actually shows the page name as: "About Us – Toronto Windows & Doors | 647-347-2842"

How can I remove this additional data?
I already removed this element from all in one seo, so there must be something else.

also i saw there is an option for priority change to overwrite other plugins like SEO plugins. is there any way to do this?

I checked in ALL IN ONE SEO’s documentation and they refer to this function:

function change_wordpress_seo_title( $title ){
    $title = 'modified title';
    return $title;
}

but i don’t know how to change this to work with my specific case…

Thanks in advance, I appreciate any help given with this issue.
