http monitor already deleted but still shows up in availability and health icons

Hello all

I have installed Appmanager 9 and build number is 9500.

I added a http url as service in appmanger9 for testing. But it was showing as down as it was unreachable. Then I deleted the http url as service entirely from Monitors.
But On the Home page under Summary Dashboard > Web server/services the 'availability' and 'health' icons are still showing red, on clicking the Root Cause Analysis message it gives 'http Url' is down. and on clicking the message it takes to nowhere coz since the http url monitor is deleted. So how to remove this RCA which is actually false. or any way to refresh

Waiting for response.

Thanks
Niyati
