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.
When I look at that same Cub in IA, I see the same parent name listed, but with 3 different email addresses. (The one in Scoutbook is an apparent typo of one of these, missing a middle initial in the gmail address)
I will send you a direct message > look at top right Avatar to find it > it will be a green envelope > it will be a private message channel with select members of the Scoutbook User Advisory Council (SUAC)
