Are some ring devices not compatible with each other?

I installed a ring doorbell pro to the front door and it works brilliantly. I then went to install a ring doorbell wired to the backdoor and it comes with a jumper to bypass the mechanical chime. The pro came with a pro power hook up that hooked into the existing doorbell.I did not put the jumper in and when I hook up the ring wired it just spins blue. No white spinning ring for setup.are these two incompatible with each other?
