Why won't this red box go away?

I use JotForm for a booking form for our travel team. We have an event lead trying to fill out the form, but whatever she does, when she gets to the date question, a red box continuously pops up and won't allow her to go any further. I have asked her to click the calendar on the left hand side, to refresh the page, etc, but none of those options have worked for her. 

Thank you. 

The user can't continue filling out your form because the "form warnings/errors" are blocking the date and input fields.

Please try to inject this custom CSS code to your form:

li.form-line-error .form-error-message {
    left: 150px!important;
}

Please give it a try and let us know how it goes.
