shortcode to display only featured ads + shortcodes for filters

Hello and thanks for this great plugin!
I am trying to display only featured listings via shortcode:

I took your example code
[rtcl_filter_listings location='2,3,4', category='3,5,6', related_listings=0, type='all', limit=8, orderby='wp_query wordpress supported' order='DES', view='list', columns=1, show_image=1, image_position='top', show_category=0, show_location=1, show_labels=0, show_price=1, show_date=0, show_user=0 show_views=1/0, pagination=0]

and changed type='all' to type='featured_only' but nothing changes: I still see all the listings regardless if they are featured or not.
Moreover, in the list I still see the publishing date and the categories even if they are set to 0.

Did I write something wrong in the shortcode?
