Installed Exchange 2010 Service Pack 3 Roll Up4 but Management console end up with different versions?

Hi,

We installed Exchange 2010 Service Pack 3 update roll up 4 in our two CAS servers using the same installers.  Both were at the same version prior to changes: 14.02.0318.001.  However, after  installation of SP3 + Rollup4, one CAS server ends up with version 14.03.0174.001, while the other one had 14.03.0123.003. 

I see this version when I open Exchange management console --> About Exchange.  But if I use the command: Get-Exchangeserver | fl name,edition,admindisplayversion both servers get same version like below:

Edition             : Enterprise
AdminDisplayVersion : Version 14.3 (Build 123.4)

Should I be concerned that on the management console they are slightly off versions? And can anyone explain to me why they end up in different versions but if I use the command line, they appear to be the same?

Thanks!
