Account not being Monitored

When I attempt to set up my computer to be monitored for my son, I click the Change Icon -

I note that it states the following account is not being monitored - Bonkers (Which is me)

So when I click change, this shows up -

If i click Uses these Logins, check Bonkers. Click OK. It doesn't do anything. I note that it says its already assigned to Bonkers.

 

If its not letting me assign this login cause its already assigned to me how do I change that. I just want this computer monitored as well as his, because he's been getting on my computer and getting into things that I don't want him to. If I go into my account setup on the website, it only has him listed. But I can't change anything about his controlls, and It doesn't even have me listed as having a computer assigned for it not to monitor. Plz help me out.
