Featured Image and Page/Post Title Not Displaying

Hello,

I had someone edit my homepage and they used the Elementor plugin to add a new header and footer. However, now the theme default style of having the featured image + page or post title does not show up on any internal pages of my website. The normal layout of featured image + title doesn’t even display when you click on a blog post. Does this have something to do with Elementor? Am I able to correct this and still use the plugin?

Here are examples of what I mean:
1) This blog post doesn’t display a title or featured image, even though I have the post set to the default template: https://peculiaronpurpose.com/2021/09/celebrating-your-small-wins

2) This page does not display the featured image or page title, even though I have the page set to the default template style: https://peculiaronpurpose.com/events

Any help would be greatly appreciated because all my settings still show that the pages and posts should be the theme settings. I am unsure if Elementor somehow overrides the theme?
