Wrong cidr in Calico IP Pool

My Calico IP Pool looks as below:

apiVersion: crd.projectcalico.org/v1
kind: IPPool
metadata:
  annotations:
  generation: 1
  name: default-ipv4-ippool
  resourceVersion: "828"
  uid: 09ed9e8a-e717-4313-9403-b351ca086257
spec:
  allowedUses:
  - Workload
  - Tunnel
  blockSize: 26
  cidr: 192.168.0.0/16
  ipipMode: Always
  natOutgoing: true
  nodeSelector: all()
  vxlanMode: Never

My question why the CIDR Notation is wrong in the IPPool?

192.168.0.0 is Class C and that is why cannot have 16 network bits. The least amount of network bits in Class C is 24.

Also, what is blockSize: 26?
