How to remove border between header and subheader?

Is there a way to remove the Sub Header border that separates the Header and the Sub Header?

You can do that by using this custom CSS code:

.form-subHeader {

    border-top: none !important;

}

Here's my cloned form with that CSS code: https://form.jotform.com/61035871967969 

This is how it looks like:

Let us know if that works.

Thank you!
