Getting SamlSSO Error when trying to select metadata components.

Any Ideas how to move past this issue?

I am trying to do the self-paced Apex training, and until I can get the metadata components to attach I can't create a new class.

I'm sorry, but I am having an amazingly difficult time doing what would seem to be an easy function in the Community Builder.  I am using the "Napili" template, which is supposed to support case filing.  However, when I am in the Builder, select the "Contact Support" page, click on the "Case Creation" element to the left, and enter "NewCase" into the "Signed-In User Case Action" box it gives me the following error:



And here is a screenshot showing we have an action called "NewCase":



Somebody please tell me that I am missing something super-simple here.

Thanks!

PS - Is it possible to customize which fields are included on the Case Creation page (i.e. can we use a form instead of a simple contact form)?
