Selecting Service does not show the correct working hours

Hi guys,

I want to explain the situation. I have several Provider Services as dummy, every service has the time configured. When I try to make an appointment for example for "Reiki" it doen't bring back the correct working hours. I was seeing that que schedule is taking a base from Working Hours at "List For: Provider not specified" It takes this base and not show that I define for service "Reiki" that is associated with X Service provider.
