Bests & Worsts Reviews from Amazon

We have a number of Alexa devices in our house and they work very well. We bought the Kids Edition for our 4-year old son. We told it "play bedtime thunderstorm" and instead it played erotica. See the attached screenshot showing it correctly understood the request. On a normal Alexa, this plays white noise. How they could they possibly build a Kids Edition that ignores the normal requests and instead plays erotica?? I contacted support who told me we should say "play bedtime stories". How is that the solution?
