I see some discrepancies in the healthchecker reports at some sites, both Exchange 2019 and Exchange 2016 where the healthckecker reports the server is not on the latest SU. The build number seems to report correctly. For instance, on an Exchange 2016 server, the build is reported as v15.01.2507.032 which is the Aug23SUv2 but healthchecker reports the SU is not installed. The only thing I can see is the build is published as v15.1.2507.032 and not 15.01.2507.032. Windows update shows KB5030524 is installed and I've tried re-installing and there is no change. Is this a known bug in the healthchecker or is something else possibly wrong?
This is what healthchecker is reporting:
