Hi,

I'm currently working on the App Customization Specialist Lightning Superbadge.
I'm stuck on Challenge 4 with the reported error of:
 

Challenge Not yet complete... here's what's wrong: 
The 'My Top Volunteer Organizations' report is not using the correct IsShiftVolunteer filter.

However, my IsShiftVolunteer filter IS set to:
 

IsShiftVolunteer equals "True"

I've tried (nonsensically) to make this equals "False" or to lock the filter, but neither of these changes helped.

Could this error description be incorrect and misleading?
If so, what else might be wrong on this report?
(Am I even correct to believe it is a problem with this report?)

Here is a screenshot of the report builder:

Thanks in advance,
