Lab 3.3 Both nodes are listed with Roles as "master". Is that expected or something need to be fixed?

kubectl get nodes
NAME STATUS ROLES AGE VERSION
ip-xxxx Ready master 11m v1.18.1
ip-yyyyy Ready master 44m v1.18.1

Nevermind, I figured out what went wrong. I passed this argument "-control-plane --certificate-key" to kubeadm join command which added my second node as master instead of worker.
I fixed it by running 1) kubeadm reset 2) delete the second master node kubectl delete node 3) Running kubeadm join command again without the control plane argument.
