Is OSPF route delete logging incomplete or am I missing it in another debug log?

[Cerebus]

Version 9.1 currently but I can upgrade if necessary.

I have debug ospf zebra enabled b/c I want to see changes to the routing table.

When a distant link that's part of an ECMP set dies and OSPF processes the LSA, it does not log the deletion of the ECMP route.

E.g., given the starting point:

192.168.0.6/31 nhid 33 via 192.168.0.1 dev eth1 proto ospf metric 20
192.168.0.12/31 nhid 34 proto ospf metric 20
        nexthop via 192.168.0.3 dev eth2 weight 1
        nexthop via 192.168.0.1 dev eth1 weight 1

If the 0.6/31 link dies, OSPF logs:

2024/09/06 20:33:41.726 OSPF: [GEBDT-G1CP1] Zebra: Route delete 192.168.0.6/31
2024/09/06 20:33:41.726 OSPF: [RDXQE-Z6A3B] Zebra: Route add 192.168.0.12/31 nexthop 192.168.0.3, ifindex=115 eth2

And the resulting table:

192.168.0.12/31 nhid 26 via 192.168.0.3 dev eth2 proto ospf metric 20

The resulting table is correct, but the log omits the deletion of 0.12/31 nexthop via eth1. Is this info in another debug log, or is this a bug?
