In JetBrains Rider (and other JetBrains products) we can Sign Off our commits:

However, after a commit and a push, the Author field erases itself.
Note that everything works as expected on remote. It’s just that locally I have to re-write the Author field.

I am connected to GitHub when I got to “Settings > Version Control > GitHub”, no issue from there.

I have the same problem with PyCharm. I assume I have something not configured properly across all JetBrains products.

How can I do to have the field not erase itself after each commit? Right now, I have to fill it manually every time I commit.
