Hi. I’ve found a fix for this. Change these two lines (477 & 495) in media-features.php
$columns['categories'] = __( 'Categories', 'media-features' );
to
$columns['media_categories'] = __( 'Categories', 'media-features' );
and
if ( 'categories' == $column ) {
to
if ( 'media_categories' == $column ) {
It doesn’t have to be ‘media_categories’, it could be ‘fried eggs’. As long as it’s not ‘categories’, ‘tags’, ‘post_tag’ or ‘taxonomy-something’ you should be fine.
