Services tabs not working

Hello, please refer to

hfsport.org/index.php/book-a-lesson#pane3

I cannot select the other services, like Rusty Rackets, just the first one is selected by default.
Also, I have defined multiple venues and assigned them to the categories, but I cannot pick the venues.

Any help?

Hi Marija,
Please go to Backend > OS Services Booking > Configuration and Select Load bootstrap is Yes. The issue will be solved
Thanks
