How to stop excerpts being automatically inserted into post page?

Hi. Im using the catch mag pro theme. Ive noticed that by default every post automatically has the post title and excerpt put at the top of page. Installing the 'hide title' plugin hides the title but it would be nice to be able to remove/hide the exerpt for most of my pages. There does not seem an option to hide it in the options. Only to shorten the length of it. This might sound small but i am importing 1000 posts. And the excerpt is duplicated twice in all these pages. Please see the link below for a screenshot. https://imgur.com/77UUjH3
