Hello, I try to finish the Trailhead challlenge Create a Unique Account List View but I have ne error like this : 

There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: MPIWTUII

I use different Developer Edition playground. But each time it is the same and my list view seems to be OK.User-added image
