I still don't get it.
Just tried setting my profile to kids, but that too works correctly.
Somehow for yet unknown reason, netflix on your end redirects the Netflix to https://www.netflix.com/Kids and then the login fails.
Is that something you can reproduce in a browser? Make sure you also try this in a browsersession that doesn't log in automatically ( by clearing cookies, using a browser which doesn't have logincookies for netflix, or in a private browser session?)
