Hi Clare, it appears they are for different people and therefore do not need to be merged.
Ah, I found the one you are speaking of (Pierson-2955) instead of 2995. Now I see.
Can you not merge them, bieing that you are the PM of both? If not, perhaps this will help: https://www.wikitree.com/wiki/Help:Merging#Merging_duplicate_accounts
Basically, it says that if one account does not have an active email address, then you can merge them here.
So in my mind, if both of your accounts have an active email address, delete one of the addresses. (I hope). Make the one you want to keep ID 2 (on the merge page).
