Services tab on booking page isn't clickable

Hi,
I have made two services - Personal Training and Massage, but on the booking page the Massage tab appears in blue and isn't clickable.
See here:

The page is: Here
click on a date like 3rd March - the Personal Training tab is there, but the Massage one doesn't work.
Can you help?
Thanks
Tim

Hi,
Please go to Back-end > OS Services Booking > Configuration and select Yes at field Load Bootstrap

Thanks Dang!
Now - if I click on the employee (for either service), nothing happens - I can't book any time....
Any ideas?
Tim

Hi Timothy,
In this case, you need to submit ticket and send your site information with super admin acc. I will check the problem for you.
Thanks
