Personalize your CRM Analytics - Challenge not yet complete

Hi,

When I go to select “Check Challenge to Earn 500 Points” after setting up a notification called “Lost Opportunities” on the Trailhead – “CRM Analytics Dashboard Navigation – Personalize Your CRM Analytics” – I get a note saying "We can't find a notification named "Lost Opportunities"... "

However I have set up the notification correctly as far as I am aware and copied the "Lost Opportunities" to avoid a typo.  I can see the notification in my notifications section. 

Please can you advise how I can move on to the next challenge?

Thanks,

David
