Multiple re-occurring events, for unknown reason

Hi,

We’re using the plugin on this website http://www.brightersound.com/, and recently the calendar has started displaying multiple re-occuring events. We’ve checked all events and they occurrences are nothing like what we are seeing.

One particular event is showing many times every single day.

Do you have any ideas what could be causing this?

Thanks,

Chris.
