I have the same issue, but I do not see this Padding setting for us. In fact our screens looks completely different for Service Providers. And we have no way to choose a Provider and edit (to see if those above settings are there) - https://www.screencast.com/t/r5bghrTUw
Hmmm... there is still an issue. I tried both methods you mentioned above (and together). Right now, it is only set to Autorefresh on Services. But, here is the problem we see: when you go to the page (http://indianrunlandscaping.com/make-an-appointment/ ) the first time it default to the first service (which is fine) and it shows the one provider (Jason, which is fine). But the Calendar does not show. Even if you click Show Available Times, it does not show times. If you switch service, and then go back to Hardscaping, then it works. Why?
Thanks, I didn't know that the Choose Service Provider did not auto-refresh based on the Service (before being clicked). I don't know how to get to the screen you showed to edit that feature. Where is it?
