Mariusz on "[Plugin: WP-Filebase Download Manager] Attach same file to another post more than once?"

Hi,
I've noticed that I am enable to attach existing file only once.

When I try to attach this file to another post, it disappears from former post.

I use <?php echo do_shortcode('[wpfilebase tag=attachments ]'); ?> on post type to display files.
