Jumpers had to be connected like I described in this post Endstop Jumpers.
But as you can see a few posts later, Tim told that they are not neccesarily needed anymore. In my opinion you would only need them when you don’t have endstops mounted and still enabled them in the web app. But that would not make any sense 
Means that you don’t need those jumpers, either use endstops and enable them in the webapp, or just disable it and its fine.
Actually I’m not really sure if this is software, or hardware related. Maybe you can figure out something
