I don't think you've been answered. You're doing a Ged compare. If they are the same person "Match". Then consider whether you want to "Skip" importing the person. That depends.
We try very hard to avoid creating duplicates. They require being merged into the other profile, and leave 'tracks' in the system forever.
In the case of Massey-2371, the profile is open privacy (the white open lock icon), you will be able to make sourced additions and corrections to this profile, without any problem. Skip that person (you did I see).
If you choose to do so you can ask to be put on the trusted list or made a co-manager of the file. If they are orphaned you can adopt them.
If the lock on the profile is green, I would still "skip" the import. Ask immediately (explaining why) to be added to the trusted list, so that you can make corrections.
