User Friendly Label For Hidden Fields With Perch Forms

I'm using Perch Forms along with a hidden field to pass a value to the forms app. It works great except for the user-facing label in the control panel and the email are using the ID instead of the specified label attribute.

<perch:input id="consultantEmail" value="<perch:forms id="emailTo" />" type="hidden" label="Consultant" />
