Ring Doorbell 1st gen setting off hardwired digital chime on motion

I've had my Ring doorbell for almost 2 years now, and it had been working great up until a month or two ago. About 1/4 to 1/2 of the time the doorbell detects motion, it will also ring the hardwired chime I have inside. It only shows up as motion in the app, and not a ring, so it shouldn't be a stuck button or anything. I've tried replacing the diode, to no avail. I'm not sure what else to try either, as it doesn't make sense why motion would set off the chime without the button being pressed. I'm wondering if the doorbell is pulling extra power when it detects motion and that is setting off the chime somehow, but I would have no idea how to remedy that. Please help!Thanks,Zach
