When active this plugin my website design breaks because of 3 lines

[TouhidApps]

    // Remove autop in shortcode
     remove_filter('the_content', 'wpautop');
     add_filter('the_content', 'wpautop', 99);
     add_filter('the_content', 'shortcode_unautop', 100);

After commenting or removing these 3 lines of code, design looks normal.
