github and git names are different, how to remedy?

[lolbinarycat]

The majority of my contributions are listed under "binarycat" (with some of those separate because of a different email), but recently i've started reviewing PRs, and those contributions are listed under "lolbinarycat".

I'm not sure how to remedy this.
