After looking at your account I can see that Sean has access to iTunes with explicit content and also Instagram in Play mode.
Although Lachlan is blocked from both of these.
If you are still experiencing issues with allowing Sean Instagram and explicit iTunes access, please give our support line a call on 1300 398 326 and we'll be happy to assist.
