The place where the metal touches the button. So the connection between board and button. Look for damage or cracks

If I had to guess the E-shoe is not around the button membrane, but most probably on the flat cable or on the connector the flat cable is plugged into.

I am guessing, by the amount of lines on that flat cable, that the buttons are just dumb switches shorting a line and have no additional intelligence to them.

If you have a multimeter you could perhaps check that continuity happens on two given lines when you press the button, to know which lines you will have to follow them visually along the flat cable, that will let you know that the button works correctly and the problem is perhaps on the connector (it may require just unplugging and plugging it again).

Other option, less likely, is that those Chinese were really clumsy and forgot to put the graphite piece of the switch inside the membrane. Just take the membrane out and check it with your eyes, if that is a case then I don't even.
