Software does not advance

Hi!

When I start the solder plate reflow (70mm by 50mm Ver2.4 ATmega328p), it shows this message on the OLED screen and it doesn't do anything else:
Solder Reflow Plate
S/W V1.0
H/W V2.4

I can't find where the problem is

Try putting in the buttons around the other way. Of the 6 pins, 4 of them are connected to one side.

There's a little notch on the button, make sure it's pointing to the left, towards the OLED/ATmega on both buttons.
