The best guess now is that Pi pin 38 is bad, somehow. The next best guess would be pin 40.
40 = The pin that actually runs the green LED and can shut down the whole machine.
I'd assume this one is working properly, because you can shut down from the main menu.
38 = The pin that connects to the ON/OFF switch. The ON/OFF also connects to some battery circuitry. When you first press ON, then the battery circuitry gets enabled which powers the Pi. Once the Pi is running, it takes over (via pin 40) and can keep that circuitry enabled. After the Pi is running, the Pi can also read pin38 to see if you pressed the ON/OFF again (like if you hold it in to power down).
So, my best guess is that there's a bad connection between Pi pin 38 and the rest of the Freeplay Zero (GPA) circuitry. It could be a bad pin, a bad trace, or bad solder.
I sent them to you via email, because I'm not able to post them here, also I think I'm might see what you are talking about and I might have messed it up by hitting the lines with the solder
