please someone have me, thanks.

I'm having trouble validating challenge 2, with regard to Shinje Tashi's user settings.
ERROR: 
Challenge Not yet complete... here's what's wrong: 
Shinje Tashi does not have the user settings he needs.

The instructions say: "This sales data quality specialist supports the entire company and needs to be assigned a role that can see and access all account, contact, and opportunity records for the entire company. Use the Standard User profile."

First off, it seems odd not to handle this through a separate profile, but I'm trying to follow the directions. So...

I created Shinje as an active user, User License: Salesforce, Profile: Standard User. There isn't a role specified for him, and the instructions suggest providing access to all acct, contact and oppty records through a role assignment, so I created a Sales Data Admin role, reporting to the CEO. That role should provide RECORD access. Additionally, for OBJECT access, I created a permission set granting full access (CRED, View All, Modify All) to Acct, Contact, and Oppty objects and assigned it to Shinje. I created a separate permission set granting access to the Language preference field on Acct, named that permission set "Bilingual Pilot" as instructed, and assigned it to Shinje.

I'm not sure what I'm missing...
