Hello @Assuritivity54385! I’m sorry to hear this is happening. At this time, there is no such export feature available for event types, though it’s a great idea and feedback I will take to our team!
When using the troubleshooting tool that you mentioned, if a buffer is the issue, it should show you the exact timeslots that the buffer is coming from. You can then go to your “scheduled events“ tab > “upcoming”, and look for that time slot to see exactly what booking is there in that time slot (and which event type it’s booked for). Then, you can look at the settings for that event type and make changes, which will help avoid this happening with future bookings. That said, once a booking has been made, the settings in place at the time of the booking will remain, even if you change them on the event type, proper. This means that in order to free up time slots blocked off by a buffer you would need to cancel and reschedule the bookings that were made with those buffers in place.
You can read more in this help center article about buffer settings, and this one about customizing your event type settings. Lastly, this helps center article about what to do when you are unavailable but should be free might be helpful! I do hope this helps you resolve your problem, but leave a comment back if you need further assistance!
