Repeating events creating the same event multiple times.

I am having the following problem.

I have created a repeating event that occurs on the 2nd Wednesday of the month. I have set up event repeat to create items 90 days in advance.

Whenever the cron runs (once a day) it creates an event for the 2nd wednesday of November, which then goes into the moderation queue.

If I approve it I get a new event for that day in November, and then the next day I get a new event in November, for the same day. So after a few days of this I get 3 events for the same time.

Why is the system creating the same repeating event?

Is there are problem with repeating events and modr8?

Is there a way of getting previously approved repeating events to auto approve?

Drupal 5.2
Modr8 5.x-2.3
