Units can have their own set of requirements set-up on them. To view how your units are set-up you can go to the "Edit Units" page and see all attached requirements and how they affect compliance.
Go to your Units screen by clicking "Units" from your main home screen. If you do not see "Units" on your nav-bar, click the "More" icon and then click on "Units" to open the Manage Units screen.
Find the Unit you would like to review, click the "Edit" (pencil) icon, to open the edit page.
In the Navigation panel, click the attached requirement to review. If there is a requirement, module, assessment, etc... attached, there would be a number showing next to that item showing how many unique items are attached to that item.
