Classified Listing request and shortcode problems

Hi and thanks for a great plugin.
I am using the Classified Listing plugin which has it’s own post type (rtcl_listing) but it also has Ad Types, which are kind of like Categories but are a separate thing that sit above categories when people are filling out the post form in the front end; would it be possible to limit posts in these, either using code or an edit to the plugin?
My set up is as follows – I have two created user roles, Business and Individual, which I have set different weekly limits on for Classified Listings, and I have 3 Ad Types, one of which I want to limit to only 1 post for Business and 0 posts for Individual, while the other existing limits I want to remain. If that is possible within your plugin as it stands, great, but I haven’t found a way to do it so far.

The problem I am having is that the shortcode [upl_limits format=”you have {left} left. “] does not show anything on the front end for Admin users (works perfectly for all other users): its a minor thing but is this a known bug or conflict? The admins have roles other than admin by the way (as listed above). I have tried both permissive and restrictive settings to see if that was the cause, and when I turned Document Statistics on the Admin users have blank entries, while other users have the correct numbers shown for their roles. Any help greatly appreciated.
