Hi, 

I am working on a plugin here http://dottieeloise.com/book-now-testing/ 

I had couple of appointments booked only for testing purposes and they appear in Appointments section (WP dashboard) but if I go to Customers, no clients appear there despite of them appearing in other sections. 

I thought that once a client booked a service with me, they would automatically appear on the list of my clients? 

I am attaching screenshots. 

Thanks,
