need [wpdm_tree] to download file from tree

Just downloaded the free version of this plugin and the Add-on shortcode plugin. I need the [wpdm_tree] to download the file when clicked from the expanded tree. It currently links to the file page; the file link on that page will download the file.

I need for the tree view to bypass going to the file pages and just download when the link it clicked on from the tree view.

Am I doing something wrong…or what am I missing?
