Chime Pro Sending Ping Of Death Packets

My Zyxel 3301 Router is reporting that the Ring Chime Pro v2 on the 5Ghz segment of my Wireless LAN is sending Ping Of Death packets. These reported attacks occur 6 hours apart and run at 1 second intervals for a total of 22 packets, (so for 22 seconds), then stop. The packet size of each is 4460 bytes.Some of the 22 packets in each block are targeted at my router at XX.XX.XX.XX, others are targeted at external ip addresses including XX.XX.XX.XX and XX.XX.XX.XX which I believe could be Amazon locations. Is my Chime Pro v2 faulty? Has anyone else experienced this?
