Selections: incorrect label in document type editor for boolean radio group

Created project using archetype 2.00.06-SNAPSHOT.
Added Selections through Essentials / setup application.
In Document Type Editor, under Primitive Types, there are two almost identical labels (see screenshot):

• radio group
• radiogroup
  The first one is the Radio Group field, the second one is the Boolean Radio Group field.
  Hence the second label under primitive types should be Boolean Radio Group.
