"Country" in a drop down menu is stuck at Venezuela!

I used the Student Registration template and in the address field there is a "country" drop down menu.  Through the process of going in and out of the Designer page, the field is now always in the default country of "Venezuela".   If it is possible to set a default country, I must have inadvertently set it to Venezuela when I intended United States. 

I have tried multiple ways in the Builder and the Designer mode to reset this to either no selection or the United States.  None have worked.

Please advise.

Thank you.

Thank you - that did it.
