Some of my fields are getting cropped on the form

When we are filling out the form, some of the fields are only showing half of the dropdown bar. For example, in the attached photo, the Quantity bar is hardly visible and only appears fully after being clicked on. 

I have tested the form on my windows browsers (chrome, Firefox and Safari) but was unable to replicate the issue.

Kindly try adding a margin of 5px between the collapsible section using the form designer then reload the form in your browser again.
