Ring Doorbell rings multiple times

When the door bell is rung, it rings on the chime and on my phone (3-4 chimes). Then, after a gap of a few seconds, it chimes again and I get another notification on my phone. So for every ring, I get 4 notifications (and 4 rounds of chimes). Would you know what could be the problem? I could not find anything in the settings to make it chime & notify 4 times Rajesh
