Hive Query with Parameterization not showing parameter labels

When I create a Hive query in Beeswax with parameters (and "Enable Parameterization" checked); the "Parameterize Hive Query" page after pressing the Execute button doesn't show any parameter labels, just blank input fields. When more than one parameter is used this is very confusing.

Sample query:
select * from sample_07 where salary > $min_salary and total_emp > $total_emp
