Dear Kittamaru:
I looked at the APM 9.7-10 release notes. There didn't see anything specific but this seemed interesting for APM 9.6:
Defect 85272 - WebView Issue with Upgrade
Valid for: CA APM 9.6, 9.7, WebView
Symptom:
If you are upgrading to 9.6, the new WebView “Home Page” displays several charts and alert statuses
that were defined in the management module Triage Map Configurations of the previous APM
releases. The older module file, TriageMapConfigurationsManagementModule.jar, is not overwritten
during the upgrade process.
Please open a case to pursue further
Thanks
Hal German
