I just received 40 email reminders, 24 twitter messages, and 20 SMS messages for one event reminder

I have one reminder that just sent 40 emails, 24 twitter messages, and 20 SMS messages. Oops. We are up to 56 email messages. I was able to go into settings and disable SMS messaging and twitter messaging. I will have to try disabling email notification too. I think that there is a problem with notifications.
