There seems to be an import data missing which is required to complete this superbadge.  Fifth bullet under Prework and Notes says, After installing the unmanaged package, navigate to the Data Import tab on the SolarBots app and select Import.  There isn't any link for importing any file?  I was in midst of doing superbadge for reports and dashboard for classic but it expired yesterday.  So I started with this lightning one now, but stuck.

Hi all,
I'm stuck on the last step of the "Build a Data Model for a Recruiting App" project (Create Custom Recruiting Fields).
https://trailhead.salesforce.com/projects/build-a-data-model-for-a-recruiting-app/steps/create-custom-recruiting-fields
I'm fairly sure I've followed the steps correctly, but I get the error:

Challenge Not yet complete... here's what's wrong: 
The field 'Leadership_Skills__c' either does not exist on the Review__c object or it is not of type Picklist.

However it definitely exist as a pick list - see screen shot.

What have I missed? Thanks very much...
