Placeholder size on page playing up on mobile version


I have included a placeholder on a page (the only thing on that page) and link ScheduleOnce for booking services. It works fine on desktop, but not on mobile.
After selecting the time, the first part of the form doesn’t come up. It comes after you try to submit and it says that you need to input the requested information. 
After you fill the form, there is no way to submit it. 
Also, not all the available timing is displayed. In this example 4pm should come up.

How can I sort this out? 


Hi Pavel, 

If you provide us with a test link for the page in question, the community here might be able to help you.

I appreciate your help very much. It doesn’t work only on mobile platform.
