Configuring Prometheus alerts causes Cluster Install page to display error message

When configuring the prometheus alerting under "Custom Metrics", there is a period when the Cluster Install page displays an error message for the Prometheus app. The status for Prometheus app now says "Install" (what happens you click that button ?!)

What should happen

Prometheus app has no error message and is still "Installed"

While the applications are undergoing the updating status, show that the application is still being installed by showing the Installing button. Do not show an error.
