What you are seeing is the extra stuff that comes with the Enhanced Movement mod. While in the main menu go to Options > Expansions > scroll until you see "Enhanced Movement" and click on that. Double clicking on "Keys" will bring you to the menu where you can then change them to a separate use action or remove them all together by selecting "NONE", be sure to double click on your selections to make sure they are saved. I also wanted to share, finding the small puzzle piece in the bottom right in the escape menu can get you there too, while in server.
