Kuberntes使用CNI(Calico)同一台节点分配了两个不同的Pod IP段问题？

# kubectl get pod -A -o wide|grep kube-node18
...

ns-demo   service-5f5b786556-xp2st  1/1     Running     0      34d     172.23.14.198    kube-node18
ns-demo   service-6b4bd8c9ff-w57ln  1/1     Running     0      5d16h   172.23.15.28     kube-node18

上述代码中的同一台宿主机，kube-node18 分配了172.23.14.198 和172.23.15.28 两个不同段的IP。如何解决在同一台宿主机上只分配一个IP段？

Calico自定义配置如下：

apiVersion: operator.tigera.io/v1
kind: Installation
metadata:
  name: default
spec:
  calicoNetwork:
    ipPools:
    - blockSize: 26
      cidr: 192.168.0.0/16
      encapsulation: VXLANCrossSubnet
      natOutgoing: Enabled
      nodeSelector: all()

apiVersion: operator.tigera.io/v1
kind: APIServer 
metadata: 
  name: default 
spec: {}
