Double entry ical

Hello,

On https://www.stadscafedebasiliek.nl I’m using this plugin combined with the Facebook events add-on.

Now, since the addon is installed, an event is added double in iCal when the button ‘add to iCal’ is used.
I don’t know the google button works because I can’t test it.

Is there a sollution for the double iCal entry?

Kind regards
René
