I am get this error: "Challenge Not yet complete... here's what's wrong: 
The 'Opp Stage by Adventure' report does not appear to be configured correctly. Make sure it has the correct report type, groupings, filters and chart type".

I believe i configured the report according to the instructions but it is still showing and error. Any assistance or insight would be apreciated. 

I installed both the Opp Alert Coponent and the ContactsToday Component from the Trailhead Module "Working with Custom Lightning Components". However, they are not available to add as components in the Lightning App Builder. I've tried uninstalling an reinstalling, with no luck. The "Custom Components" section in Lightning App Builder shows 0.

Any help would be appreciated - I've had nothing but technical difficulties with this module and I want to earn that darn badge already!
