Thank you.
This is because of CSS coming from your theme. More info in this video.
Here’s some CSS that should make things how you’re wanting:
body.post-type-archive-tribe_events .entry-summary {
clear: none;
}
You can add custom CSS code via your child theme’s style.css file or via a plugin like Simple Custom CSS or, my favorite, Jetpack. Jetpack supports regular CSS and the LESS and Sass pre-processors.
If you’re not a CSS expert, Jetpack’s Custom Design reference may prove helpful.
Please let me know how it goes for you.
