Multiple Class Service Times Not Showing

My client has three types of services that she offers.

They can be viewed here - http://www.oxsalon.com/members

Her Semi-Personal Training Session times appear fine. The other options show blacked out dates.

We tried to associate dummy providers for the other two types of classes (one-on-on and oxcamp) as well as setup their working hours.

Still not showing. Please advise.
