Parent magic mailing list looking at deactivated users?

I have several families that’s appearing in the Parent magic mailing list. There are two members of each household, the parent and a scout who has aged out. If I understand correctly, they should not be in the parent list.

I’m wondering if the magic mailing list is looking at the deactivated users. And if so, should it be?

I tested this by creating a test scout, and assigning it to someone who isn’t on the parent list. That individual showed up, even after deactivating the test scout. The adult didn’t disappear from the parent list until I deleted the test scout.

I’m sure sure if this is a bug, or desired functionality. To me, it’s a bug, but I can see a rationale for it being desired also.
