Ultimte Facebook

When using Ultimate Facebook plugin shortcode [wdfb_events for="x"] the plugin seems to change the time and date of the FB event when it pulls it through. If I change the API settign to one of a different app the dates and time change but are still incorrect. No matter what i try the ned date seems stuck at Ends at: January 1, 1970 12:00 am
I can't seem to get [show_end_date="false"] to have any effect either.
