Haven't checked the most recent version, since I'm no longer needing to use this module in my project, but I discovered that in 7.x-1.0-beta6 the "Set the redirect target of the form" action overwrites the default System > Page Redirect.

Try adding a dpm($data) before the return in rules_fetch_data() and checking out $data['action_info']['redirect'] to see what I mean. Looks like an issue a simple namespacing fix could resolve.
