[Plugin: CSV Importer] custom field import and dropdowns

this plugin seems to work great but if I have a custom field that is represented as a dropdown (using woo themes content builder) the value doesn’t come across for the drop down. It is correct in the DB but is not reflected in the drop down. Any thoughts on how to get the drop down to show the correct value?
