Need Help with "Control Access to Fields" Challenge – Permission Set Field Permissions Not Being Recognized

I'm currently stuck on the Control Access to Fields Hands-On Challenge in the Data Security module and could use some guidance. 

Challenge Requirements: 

Create a permission set with: 

Label: Manage Job Applications 

API Name: Manage_Job_Applications 

License: -None- 

Enable Job Application Object Permissions: Read and Edit 

Enable Job Application Field Permissions: Users can view all fields and edit all fields, except they can't edit Position and Candidate 

The challenge keeps returning this error:
