How to get page text below page header

Good morning,

I am having trouble figuring out how to get the text I have entered on a page to display beneath the page name. I am using WooCommerce for my cart, so it is possible this has more to do with that plugin than the theme, but any advice you offer would be most appreciated.

You can see an example of what I mean here: https://millertacticalgroup.com/sandboxx/?post_type=product

I have tried placing this text into the “Subtitle” box on the page screen but then the text just disappears completely.

Thank you.
