MailChimp Integration with unlabeled fields

I am trying to integrate a form with MailChimp, but many of the fields on the form are unlabeled. So, when I try to connect the fields with the correct MailChimp fields, the list is made up of blank choices (see the image below). Is there a way to identify the fields without editing the form's appearance?

Leaving the form field's label/question names blank or empty is susceptible to many anomaly. So we highly recommend not doing this.

Always put labels to the form Field Names for optimum performance of the form.

If you want labels to be hidden as needed by design, you can simply make them invisible using custom CSS codes.

Example:

.form-label.form-label-auto {

    visibility : hidden !important;

}

.form-line {

    margin-top : 0px !important;

    margin-bottom:0px !important;

}

Hope this help. Let us know if you need further assistance.
