Submissions not being trashed

Hi,
I have set submissions to be deleted after a set number of days but this is not occurring. From the knowledgebase on your site it says to check that wp cron is setup correctly; I have the WP Crontrol plugin, and the only cron on there for your plugin is ws_form_wp_cron_action_database but there is no action attached to it. What should the action(s) be, or additional cron as I can edit/add arguments/crons in the Crontrol plugin, but you should maybe be aware of this in case there is an issue that needs fixing?
