If an error occurs (formRule) while adding a field of type "Phone and extension" the "Location Type" drop down is hidden when the form is re-displayed

If an error occurs (formRule) while adding a field of type "Phone" or "Phone and extension" the "Location Type" drop down is hidden when the form is re-displayed.

To replicate add a field of either of those two types and blank out the required order field. Note: Any other error will have the same effect so it is not just the order field that causes this display issue.
