Redoing a extra merge and a accidental contribution from the wrong user <p>I have the following git history that I would like to sort out a bit:</p> <p><a href="https://i.stack.imgur.com/9CoeS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/9CoeS.png" alt="Git History"></a></p> <p>The issue occurred by using a remote editor fixed to a different git account but that had permissions for mine. Thus there are two contributors but they are both me. I then tried to fix that issue and got the red and black overlap looking commit instead. Then somehow I managed to pull and do a merge duplicating the results with a merge (the actual merge). The merge says that no changes occurred. Is there anyway I can clean this up and reassign credit just to black user not red user? I'm sure I'm skipping over details but I am not sure what else is relevant. Thanks! </p>
