In "Keep Data Secure in a Recruiting App" trailhead project, on step "Restrict Data Access with Field-Level Security, Permission Sets, and Sharing Settings", I have got the following error :

Review the instructions for setting the Job Posting status to 'Read/Write'

Did someone faced that and how to fix it ?

There's something weird. on the last screenshot regarding (Sharing settings), I see that Job Posting is "Public read only"
But this object is a junction object and following the steps won't give access to this setting but "Controlled by Parent".

I'm don't understand what "status" is referenced by the error message. There's a status field on Job Posting Site object as well as on Position object but not on Job Posting which contains only 2 master details fields.

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