Can't Display Category Title on GD Archive Template Page Using Divi

I am basically having the exact same issue this person had: https://wpgeodirectory.com/support/topic/how-to-display-category-page-title-on-archive-template/

Using Divi, I have two text modules in the GD Archive template. One text module contains all the default shortcodes that come in the template and the other contains the [gd_post_title] shortcode but it doesn’t seem to be working. Now when I go to category pages on the front-end it simply says “Page Category:” but not the actual category. I want to have the category displayed as the page heading just like the rest of my pages so naturally I would want to get rid of that “Page Category:” pre-text in addition to just getting the category title to display at all.

If this requires some PHP modification, please point me in the right direction. I have a geodirectory folder in my child theme with a few template files already and have done edits before so I’m comfortable working with it. I’d just need to know what to edit/add and where.
