Exchange Version Showing The Wrong CU After Upgrade

I've run into an odd issue after performing an upgrade from Exchange 2016 CU14 to CU16.

I have two servers running and both successfully upgraded to CU16 with no errors, however I noticed that both are not showing the correct AdminDisplayVersion for each other.

Both servers are showing the correct build number for themselves (1979.3) when I check Get-ExchangeServer | fl AdminDisplayVersion

However if I run this command on EX01 it will show me that EX02 is on the wrong build version (1847.3) and vice versa if I run the command on EX02.

Programs and Features show the correct CU Version is installed.

I'm at a loss. Any ideas?
