When I am in Realize why do I see two classes with same name?

Realize will create a corresponding Savvas Realize class based on your LMS course. You cannot link your Canvas course to an existing class in Savvas Realize. If you already have the same class in Realize you will get a duplicate class. However the Canvas created class will end with "(LMS)" so you can tell the Canvas created one apart from your EasyBridge class. 

You can hide your non-Canvas class in Realize. If you ever want to assign something directly in Realize you can with your LMS created class in Realize.

Remember that class in Realize that is linked to Canvas will only contain assignments started by a student.

To hide a class simply click the Hide class link.

Once it is hidden you will find your class in the Hidden tab. You can always unhide if you need to access the class assignments.
