StaticRoute CNI calico doesn't detect multiple blockaffinities

[skenderidis]

Setup Details

CIS Version : 2.18.1

Description

I am working on a rancher environment that is using calico and CIS is configured with static routes.
Everything works fine until an additional blockaffinities is created for a specific host.
CIS doesn't create an additional routing entry for the second blockaffinity

kubectl get blockaffinities

rancher1-10-221-23-64-26    506d


kubectl get blockaffinities rancher1-10-221-23-64-26 -o yaml

kubectl get blockaffinities rancher1-10-221-23-128-26 -o yaml

Expected Result

CIS should populate multiple blockaffinities per node
