All appointments show up as unavailable

I'm having some issues with the appointments not showing up as available. I have it set to be available from 8am-6pm M-F for two users. No available times are showing up and one of the service providers is not showing up either.

I will also have a more advanced question on scheduling once I can get this part up and running.

Thank you!
