Have you included pull-up resistors in your circuit? From memory, the overlay doesn't enable internal pull-ups because they are unlikely to be strong enough to be reliable.
To confirm that some pull-ups may help, use the pinctrl utility to temporarily enable pull-ups on your bus pins and see if the readings improve.
