Exchange 2016 CU 23/SU Update Build Mismatch

Question

After updating to Exchange CU 23 and applying the Aug22SU the build number reported by the PowerShell command Get-ExchangeServer | Format-List Name,Edition,AdminDisplayVersion is Build 2507.6 while one would expect to receive 2507.12. Running the Get-Command Exsetup.exe | ForEach {$_.FileVersionInfo} provides the expected results. Is this mismatch something we should be concerned about?

Answer 1

thats expected.
Run the healthchecker to verify you are at the latest:

The AdminDisplayVersion does not consider security updates:
