@JasonKracht- the announcement in change log mentions that adding siblings would be prevented. I would gather that someone in your unit had added siblings?
@JasonKracht I recommend asking your local council to use their Registrar Tools to remove the sibling relationships. They were intended for adult siblings who might be driving a younger sibling to Scouts, etc. and who might need to be on the e-mail list.
Yes, the parent is listed in the Scout profile as shown in the images submitted. However the Parent is not linked to the Scout in the messaging part of the system.
