Getting an error for create unique account lists challenge

I'm getting the error:

"Step not yet complete in My Trailhead Playground 1

In the Energy and Biotech Accounts list view, we can't find all accounts displayed."

I have a list of 4 accounts under the filter (1 biotechnology, and 3 energy). When I look at the full list these same 4 accounts are showing. It does not appear that I'm missing anything.

Anyone know why I'm getting this error?

Thanks
