In metric viewer can see discrepancy in the dates as shown in below example
Release : 20.4 (base version)
This issue is resolved in 20.4 CU1
In case still running 20.4 base version (and not yet ready to upgrade to full CU or latest CU) workaround suggested is to deploy the the ump_operatorconsole-20.4.1.zip only from the 20.4CU1 release
