Is the input manager in unity 2018.3 just broke for controllers?

I updated from 2017.4 to 2018.3 but I was using Xinput.net, which worked fine, so I didn't notice.

I was still using 1 button from the input manager tho cause I just needed a button input which could come from any controller, and that suddenly didn't work anymore.

So I tried to check some other buttons and noticed that the buttons only register when you push them together on both Xbox controllers??

None of them work separately. I even created a new project and just added this in update

Code (CSharp):

1. if (Input.GetButton("Submit")) {
2.             print("Submit");
3.         }

Nothing happens unless I push the button on both controllers.
