I am deploying OpenShift Dedicated (OSD) using OpenShift v4.12.14 

v4.12.14 

The issue is always reproducible. 

1. Deploy OSD in either AWS or GCP (doesn't matter.)
2. Login into OpenShift Console
3. Search for ClusterAutoscaler API from "HOME > SEARCH" in the left navigation bar.
4. At this point you will only see the default ClusterAutoscaler. Now click the ClusterAutoscalers in "ClusterAutoscalers > ClusterAutoscaler details". Here you will see a blue button at the top right to create a new ClusterAutoscaler.  

As per OCP v4.12 documentation, there can be only one Cluster Autoscaler per cluster. So, I am not sure what are the use cases of showing a button to create additional ClusterAutoscalers. I would love to learn about the use cases (if any) for creating multiple ClusterAutoscalers.

"Because the cluster autoscaler is scoped to the entire cluster, you can make only one cluster autoscaler for the cluster."

https://docs.openshift.com/container-platform/4.12/machine_management/applying-autoscaling.html

There could be a use case to create a new ClusterAutoscaler when the default one is deleted. However, in that case, clicking "Create ClusterAutoscaler" should throw an error when the default ClusterAutoscaler still exists.
