New to Ring please help

Hello,I purchased 2 of the black hardwired Ring doorbells (front / rear of house) and a compatible transformer and chime from.Hampton Bay.I wired transformer to 16 as directed , installed chime here is what I found..FRONT - Rapid blinking blue , then flashing white when trying to connect.REAR - Not lighting upChime - Repeatedly ringing until I shut off breaker.The Ring instructions for this model say not to use a diode and do not mention a round wire resistor.. Am I missing something to make these components work as one system?
