Eero doesn't include IPv6 in activity

The Eero 6+ (model R010001, software v7.6.3-103) shows network activity for client devices, but I've recently noticed that it doesn't include IPv6 traffic in there.

IPv4

[ ID] Interval           Transfer     Bitrate         Retr  Cwnd
[  5]   0.00-1.00   sec   100 MBytes   842 Mbits/sec   61   2.12 MBytes
[  5]   1.00-2.00   sec   106 MBytes   891 Mbits/sec    0   2.30 MBytes
[  5]   2.00-3.00   sec   106 MBytes   891 Mbits/sec    0   2.45 MBytes
[  5]   3.00-4.00   sec   106 MBytes   891 Mbits/sec    4   2.50 MBytes
etc

IPv6

[ ID] Interval           Transfer     Bitrate         Retr  Cwnd
