Why are parents mobile numbers showing up on their kids profiles in Churchteams?

This happens when parents use their mobile phones to register their kids for events or services. Our recommendation is that they only use text-to-register or text-to-attend when the person who owns the phone is attending that event or that the first registration is for the parent and the second is for the child/student. Also, for attendance, parents should not use their phones to take attendance for their student as it should only be used if they student has their own phone.
