Hi Deborah, Welcome to Wikitree!
I'm no expert either, and I don't know what you're seeing, but I think I have proposed a merge for your duplicate uncle, This should generate an email to you, as the profile manager for one or both of the duplicate profiles. You can click the link in the email to find the screen where you can approve the merge.
The Privacy settings prevent other users from approving it. This happens because other members of Bobbie's family may still be alive. As you work backwards in time, and there is no risk of a person still being alive, the system opens up..
If the proposed merge doesn't work, you can contact info@wikitree.com via email. It helps them if you provide the url in your request for help for one or both of the profiles you are looking at. This can be the whole path (www.wikitree.com/ etc) or simply the profile reference: Stetser--10 and/or Stetser-11 that you can see on the top menu.
Hang in there! When I first joined, I was confronted with duplicates and errors that already existed. Once I began to learn how the system worked, it became easier to straighten things out. My key message is that there are other people bumbling along in Wikitree who are just like you, and we help each other out when we can.
