Permissions Issue

TJ Helms couldn't see SQL of a question he created and I had him set up in the Developer user group yet Kayla Test who is only a default user could see SQL.

I looked at our permission settings and saw I had neglected to set Developers SQL Queries for access, so I changed it and then TJ could see the SQL.

However, I don't understand how Kayla Test can see the SQL queries.

Please advise.

I have attached the permission and person settings, along with a screen shot of Kayla being able to see the SQL.
