Lynna McMillan - Did you look on the profile itself to see if you were listed as one of the managers? Because checking profiles close to you, I see you as a manager (primary or co-manager) of most of the unclaimed profiles I checked - def. more than 2.
Your mother has a claiimed profile - so either she is the only one who can edit it (the default) or anyone in the family can edit it -- depending on choice she makes in her Account Settings. This is true for any claimed profile - a claimed profile being one where the actual person it is a profile for has logged in to that profile [so your profile is said to be claimed by you, my profile by me, your mother's profile by your mother - all three of them are claimed profiles)
Can you give links to some unclaimed profiles (in Tree View, claimed have blue border around profile photo area - unclaimed do not) where you know you used to be a manager, but now you are not a manager?
