Hello friend, what you should do is to replace your gitlab username to your personal name, let’s say instead of configuring as follows:
git config --global user.name "muelasvill"
you do it this way:
git config --global user.name "John Doe"
note the blank space, it is mandatory.
in addition to that you must also verify that your data appears in the .mailmap file.
they are sorted alphabetically, if you don’t find it you must add it this way:
John Doe <jdoe@gmail.com> John Doe <jdoe@gmail.com>
