I just installed and activated my Calendar PRO and Eventbrite Add-Ons. I imported my event from Eventbrite and finished everything out.
My Details display is looking very crazy though.

There are 2 colons being injected after the details, I had to delete the $ from the settings in order to stop the double $, and the price is listed $10 – FREE. Maybe Free should be first?
Changing the Events Template from Default Events Template to Default Page Template seemed to resolve a couple of spacing issues, but overall is still very wonky.
I have provided a link to the exact event I’ve created. Here it is as well: http://bgcccpartners.org/event/kramers-new-century-bash/2015-05-09/
