Post Titles Messed Up (Words are Overlapping)

My post titles are overlapping (words displayed on top of other words) and I’m not sure how to fix this. Link for reference: https://brainygains.com/why-cant-i-lose-weight/.

I’m also wondering how to move the post title to below the featured image. In each blog post, there was an option to “Set featured image position to ‘Below Post Title'” but for some reason I’m not able to do that anymore. How can I make this work?

I currently have the Bloggera demo on my site.
