Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
I am the troop UAC I am working on advancements, I have full access to all of the scouts on the roster with the exception of two. They happen to be brothers. this is the message i get.

@SamuelMiller3 - so you are actually not in scoutbook but rather internet advancement. Has someone checked in scoutbook itself to see if their membership section has just one active and approved membership.
Beyond that if you could post the bsa ID of these scouts.
