Catagory Associated With Widget Not Updating

Summary

Our catalog and search widgets are updating with the new courses that we have added to the catagory.

We have been using the catalog and search widgets to create a course library. We add new courses to the root category and they show up in the catalog and are available by search. In the past we have experienced a delay up to a few hours for the courses to show; this week the courses are just not showing up. We tried to add the new courses yesterday and they still aren't available.

The widgets update just fine. I have tested adding new categories to the widgets and that works but the new courses aren't showing.
