Get services and employees to display on front end

Hi there
I cannot get more than one of the services to display or any of the employees to display on the front end. I have assigned employees to services, set availability and gone through the settings over and over with no luck.

I expect this will be a simple setting, but I cannot find it, so would appreciate some help on this.

I am also trying to sell appointments in packages of 3x1hr sessions, 6x1hr sessions and 12x1hr sessions and I am not sure how to configure OS Booking for this.

Cheers
Robin
