Foolproof way of lining up your paper: cut it to the exact dimensions of the circuit board.

Dude you measure voltage between GND and GPIO, or you get the voltage difference between signal level(0 or 3.3V), and 5V which is 5V or 1.7 give or take a bit, and ± sign depends on lead orientation. There's nothing strange about this, only ignorance...

Yes, I know that now. I was reading the GPIO pinout upside down, because I am an idiot... Sorry to waste your time! :)
