Ok, so I changed the variable from description to “text”
I changed the single posts element to
<center>
<h1>
{{custom_field.text}}
</h1>
<h4>
<i>Last Updated: {{post_date}} </i>
</h4>
</center>
and I changed the page hero element to:
<h1>
{{custom_field.text}}
</h1>
But still not showing up for some reason
