SVG not displaying in Media Tab in Backend

I addes this code to allow SVG Uploads to the Media Library of wordpress:

function upload_svg ( $svg_mime ){
$svg_mime['svg'] = 'image/svg+xml';
return $svg_mime;
}

add_filter( 'upload_mimes', 'upload_svg' );
define('ALLOW_UNFILTERED_UPLOADS', true);

Than I added some SVGs to the Media Library. Using them works perfectly fine. The only Issue I have is that they will not be displayed in the Media Library. On other Pages in the Backend they display fine.

Is there anything I can do to display them in the Media Tab aswell? I couln't find anything online on how to fix this issue.
