Hey hotcity,
Thanks for reaching out to us!
I just tested out our additional fields and they appear to be displaying properly on my local development site. To verify, once created and an event has been added which use one of the additional fields, the information associated with the fields will display within the “Details” section of the single event view (https://cloudup.com/cI7YVsynOgl).
If that’s not working, an initial step is to try our Testing for Conflicts procedures to ensure the issue isn’t caused by a plugin or theme conflict.
Let me know if this helps.
Thanks!
