Hi, I’m not sure if this a known bug or something but..
If I create a venue or organizer and set it to default and create a new event, the plugin fills in the venue information from the default venue, and creates a new venue instead of just using the pre-existing venue.
This does appear to be a bug – it’s filling in the fields with the correct default but not selecting the default in the drop down and instead adding the defaults as new items… I will go ahead and log this as a bug ticket. Thanks for reporting!
