The Insercorp Development Team has released an update to the Page Manager that fixed bugs with the Meta Titles and the Subpage Navigation

Content Manager 2.1.5

Bug Fixes

• Previously when a parent page had Subpage Navigation disabled yet a child page did not, the links in the side-menu did not generate properly, only showing the link to return to the top most parent page. We have fixed it so that the full side-nav generates on any page that has Subpage Navigation Enabled even if its parent has it disabled.
• Previously when Website Administrators added anything to the 'Title Tag' field of the 'SEO Meta Data' tab of a content page It would add the title tag twice. We have fixed it so that the 'Title Tag' is only added once.
