Formatting issue on scheduling page

I have installed on 3 seperate PC's (XAMPP) for testing.  On each one, the formatting of information in the drop downs i s off.  Is there something I'm not doing right?

Hi Steve,
It's the CSS conflict issue between Bootstrap library and your template. You can add Custom CSS in OS Services Booking to increase the height size of the dropdown select list to solve this minor problem.

I have never done Custom CSS,,, can you tell me where to enter it,, and I'll learn how?

Thanks

Hi Steve,
If you open OS Services Booking Configuration, you will see tab: Custom CSS. You can add custom CSS stylesheet into that form. And in future, when you install newer OS Services Booking version. You custom CSS won't lose.
Thanks

I reinstalled site from scratch. Now it works,, Maybe the template (Purity IV) did not install correctly.
