Hi @Begford,
I hope you are well today and thank you for your question.
The theme is compatible with the Elemetor and you can use the elementor to create pages.
It seems from your shared screenshot that you have created the page using WPbakery page builder therefore it displays the WPbakery shortcodes.
Please note that you can only edit the page using the same page builder that you used to create it so if you have used WPBakery or Unyson or any other page builder then please use the same page builder to edit the page.
Please do not switch between page builders or else you will lose the content so choose the page builder that you want to use initially when you create the article content.
Best regards,
Shufflehound team
