Different calendars not showing

Hello,

I signed up for the free trial, made the update and now my two different calendars for my two different services ar not working properly, what I mean is I don't have two calendars anymore, when somebody makes a reservation for a service at a certain time it occupies the time slot for the other service as well. I have written my question in the support forum of the plugin and they sent me here insted of trying to help me. The weekend is the time when I get the most reservations, and it's not workink properly.... please help me...
