You have created a new Dean, instead of editing the current Dean. No big problem, just something to try to avoid in future.
You should merge the two profiles. Meaning you merge the new profile into the old one. You have reclined the first merge request. I have initiated a second one. Please confirm it, and then merge the biography information and expand the location information as asked by the other WT member. There should never be duplicate profiles on WikiTree, this is very different from other websites.
Please read up on the documentation on unique profiles and merging.
