So some odd reason my results page is fine with my custom post types, but for the default post type, it is duplicating/closing the <a> and creating the below output. The output should only be 1 <a> element wrapped around the content. On the same search results page, the other content types are all fine.

Unexpected output:

<article id="post-956">
    <a class="box test box-hover bg-orange" href=";>
    </a>
    <div class="container-fluid">
        <a class="box test box-hover bg-orange" href=";>
        </a>
        <div class="row no-gutters"><a class="box test box-hover bg-orange" href=";>

This is the content of the search.php
