Hi! I took a look at that page and indeed found many extra Paragraph tags that our plugin itself would not be generating.
So, to truly resolve this issue and get things looking fine, you will likely need to make further code customizations to get the design right, and/or contact your theme developer for assistance regarding the addition of these empty paragraph tags. We cannot help with code customizations or with software we do not make, so please do reach out to the theme author for more support and—hopefully—a true resolution to these problems.
With all of this being said, however, try adding the following bit of CSS code to the bottom of your theme’s style.css file:
article #tribe-events p {
display: none !important;
}
This code should help remove the paragraph tags from inside events content.
I hope this helps!
