I don't know why, but Trailhead does not see that I've setup a user Samantha Cordero with the profile Field Sales User. I've create the Field Sales User profile, created the user Samantha Cordero, activate the user, generate a password, and logged in as the user. I even logged in as her in Salesforce 1, but I still get this message:

Here is what her user detail page:

Stuck in challenge 4.Can anyone help me out!!!

Hey All, 

First time posting here, I look forward to what I can learn from the community.  I am a mostly self taught Admin so I suspect my issue stems from some of the common knoweldge gaps that newer self taught types can have.  I've read post after post and watched countless videos and can't figure out the small little thing that is hanging me up on this. I also see that this doesn't seem to have spell check so all you grammer hounds please grant me mercy. 

First, since language changes on these modules I'll post the step for future readers and then the error I'm getting.

2)
Set record-level security settings
Configure other Salesforce settings related to record-level security to meet the business requirements.
Create a user, Samantha Cordero, and assign her the Field Sales User profile and the Field Sales role
Create an opportunity owned by Samantha with the stage name 'Needs Analysis'
Create a Closed Won opportunity owned by Samantha, with the type of 'Existing Customer - Upgrade'

The error on the apex test thing I get: "Assertion Failed: Field Sales users should not be able to read Opportunities owned by someone else. However, the test returned records not owned by the user. #sadtrombone: Expected: 1, Actual: 3"

So here are the few things I've drilled into and checked, I honestly can't think of anything else that I'm missing. Other parts of this could be messed up but as far as relation to the error thrown I just can't find it. 

1) Issue with the Profile, "Field Sales User". I don't think this is it due to the error throwing a lower case "user" which makes me think it's an issue with roles. Also this doesn't really have much to do with viewing rights beyond basic allowance so.. eh. Honestly I'm not even sure the best way to approach Profiles vs Roles, but again, noob here. In this profile I have the Opportunity object checked for everything except "delete" as the trail ask. 



2) Roles. Now here is where we get to the good stuff. I've checked the hierchy and have tried to mark that lowly field reps are not worthy of viewing other's opportunities (humor y'all).  For your consideration here are shots of the hierchy and the field where I marked them as unworthy.

3) Sharing Settings. This is the last area I know of to deal with this error.  I have set Opportunities to private. This, in combination with the other rules really baffles me as to why field reps can still creep on other opportunities. For visual confirmation: 



Any help or hints would be much appreciated on this.  In the event I make it out to Dreamforce and the lucky person that helps me out the most does I will gladly buy you a beer or coffee or heck even both! 

Cheers.
