SEO Meta Description not saving and not displayed on the right side below the image in SEO Optimize Popup, I'm working on 12.0

Code Block:

<meta t-if="main_object and 'website_indexed' in main_object
    and not main_object.website_indexed" name="robots" content="noindex"/>
<t t-set="meta_description" t-value="main_object and 'website_meta_description' in main_object
    and main_object.website_meta_description or website_meta_description"/>
<t t-set="meta_keywords" t-value="main_object and 'website_meta_keywords' in main_object
    and main_object.website_meta_keywords or website_meta_keywords"/>
<meta t-if="meta_description or editable" name="description" t-att-content="meta_description"/>
<meta t-if="meta_keywords or editable" name="keywords" t-att-content="meta_keywords"/>
