Hi,
I mean: by default, our theme contains the function the_content() inside it when you edit that page by using Elementor.
But, your listings plugin you're using has been overriding the content template from our theme for that page: https://mummafitnessdirectory.com.au/submit-listing/ and making it can't be edited via Elementor. You can try to create a new page ( Example: Submit Your Listing ) and you can edit it normally.
With this problem, you should contact the author of the plugin and ask them about this. It's not a problem that can be controlled by our theme.
Best Regards,
PenciDesign
