It would seem one of the profile managers has not completed the merge.
This happens when two profiles are managed by two different people.
Go to help click help index click merging and read the details of doing a merge. http://www.wikitree.com/wiki/Merging
If you aren't on the Trusted List for both profiles, you can initiate the merge but you can't complete it.
You will be invited to propose it, i.e. to create a Pending Merge. The appropriate Profile Managers will be e-mailed so that they can approve and complete the merge.
When you propose a merge you are giving permission for others to complete it. You are also giving temporary permission for five generations of ancestors of the profile to be merged. See the section on merging parents below.

If a Pending Merge is ignored for over 30 days — if the Profile Managers do not complete the merge, reject it, or set the profiles as Unmerged Matches within a month — it will be cleared for any Wiki Genealogist (any signer of the Honor Code) to complete, reject, match, or remove it as they deem appropriate.
