Hello, I'm trying to complete the challenge for the "Group and Categorize Your Data" challenge, and there is an issue with the instructions for the "Use Buckets" portion. In the fourth step "(For the third range (> 100,000), in the Name field enter Large)", it didn't offer a specific number to include. And the you must enter text into the final field, which is left blank on the instructions. When I tried to complete the challenge, I got a message saying that it couldn't be completed because: 
The 'Pipeline Matrix Report Current and 2 FY' report does not appear to have the bucket field configured correctly.

Can someone please help troubleshoot? Thanks!

Wwhen I work on the module of Group and Categorize Your Data, the following coninually come out:
Error: The 'Opportunities by Rep and Close Month' report does not seem to grouped on 'Close Date' by Calendar Month.
But I have cheked lots of times, I did grouped on the "Close date" by Calendar Month.
Who can help me and tell me why?
Thx so much!
