I have encountered a problem where if you show a section that was hidden several control types will become broken. So far the only controls that seem to have issues are check boxes and option buttons. The problem isn't limited to controls in the once hidden section all controls on the form are affected regardless of where they are. It only happens when the form is being viewed on the SharePoint server when I preview it in Infopath I don't have this problem.
Any help with this is greatly appreciated.

EDIT: I believe I should clarify what I mean by broken. It seems that the controls are no longer bound to values. Such as the value is not being updated when the form is saved.
