Hello all, I receive the following message in Trailhead. I think that the exploration and filter are set up properly. I don't know what I am doing wrong. Would you please help?

​I keep getting

Challenge Not yet complete... here's what's wrong: 
The 'Top Laptop Industry' lens was not found. Please follow the requirements and ensure everything is setup correctly

I have named the Lens as step 2 - Enter D01 - Laptops Salespeople - Wall of Fame as the title AND/OR result set Top Laptop Industry

Neither seem to work. I have refresed the screen, even cleared cookies and rebooted the computer.
