Archive Title – Substitution Not Working

I am using CPT UI to create a custom post type. I have then created the relevant Archive page in Elementor. All is working apart from the meta data.

The archive Rank Math page is setup as “%term% Archives %page% %sep% %sitename%”

However, the substitution is not working. The following is in the source for the page;

<title>%pt_plural% Archive %page% %sep% %sitename%</title>
<meta name=”description” content=”%pt_plural% Archive %page% %sep% %sitename%”/>
<meta name=”robots” content=”noindex,follow”/>
<meta property=”og:locale” content=”en_GB”>
<meta property=”og:type” content=”object”>
<meta property=”og:title” content=”%pt_plural% Archive %page% %sep% %sitename%”>

Thanks
