Got a small problem with using winches attached to anything. When I hit eject, it moves out a fraction of a meter and stops, the length gets set to max in the ui as if it has ejected its whole run, if I hit plug mode it to change it to undocked it moves a fraction more and then the length resets to less then a meter of extension on the ui. I can hit release and it extend normal then, but if I retract it all the way back into the winch it resets it, so it behaves the same way again, with eject not working. What am I doing wrong here? Is there something I'm missing? Imgur link for details : https://imgur.com/a/zFjsQ
