Controller Input Method bugs on Mirror Tablet

So basically I was playing a couple hours ago, trying the controller input method out on my tv (saving my old bones back), and found out that it doesnt show the side panel with the tiles that u can choose from and then place on the tablet, tried all buttons (because the reflector only shows when u press right analog, which I found to be also really strange)

So yea, if I need to repeat the bug and then take some screenshots, please do tell!
