I'm working on this module in trailhead:

https://developer.salesforce.com/trailhead/project/quickstart-app-builder/quickstart-app-builder3

In Lightning Builder, it says:

"From the Custom Components list, drag the ContactsNearby component to below the My Top Accounts Filter List in the left column."

I do not see that component, ContactsNearby. All I see is ContactsToday and Opportunity Alert.

Any ideas?
