CRM Webform Hidden Field Issue

CRM Webform Hidden Field Issue

I've noticed that when I create a webform and add a field, set it to hidden, and choose the field response the form isn't saving it correctly.

Example:  I create a webform and add a drop down field for lead status and make it hidden.  I choose Website from the drop down so that when the form is filled out and passed to CRM it will show Website for me under the lead status - but it won't show the field to the customer when they are filling it out.  The problem is when I make a choice from the drop down and save the form, the field is added correctly but has a blank for the choice.  At first I thought I just didn't save it but I've tried several times now and it does the same thing each time.

Any ideas?
