Update to 3.2.3 broke my site (class-box.php)

When this update to the Boxilla plugin was made to my site the GDRP banner I created as a box the boxzilla-content DIV tag was not closed and thereby the whole page content was inserted into my banner (box).

I found this use of the apply_filters() function was the root of the problem. After commenting out line: 198 of src/class-box.php file everything worked as expected.

/** 
        * Default WordPress filter for post content (so plugins like Jetpack Photon works).
        *
        * @param string $content 
        */
        //$content = apply_filters( 'the_content', $content );

The page I need help with: [log in to see the link]
