Hi Scott,
I would recommend you to use Widget instead of an inline control. From v6 widgets should replace inline controls.
In v6 you can add the (Biz)Form to the page right from
WYSIWYG/CK Editor and the modify the widget properties via
CMSSiteManager -> Development -> Widgets -> Forms & Surveys -> On-line form -> Properties -> UseColonBehindLabel -> enable "Display attribute in the editing form"
after that you will be able to disable this option in the Widget (Form) properties.
Best regards,
Martin Danko
