vSphere Client reports incorrect version of vCenter Virtual Appliance

vSphere Client 5.5 reports incorrect version of vCenter 5.5 Virtual Appliance. For instance, vCVA build is 1891314, but in vSphere Client 5.5 GUI shows as 1891313 or vCVA build is 2170515 (latest U2a), but in vSphere Client 5.5 GUI shows as 2001466.

I updated the client to the latest build 1993072, but it didn't make any difference.

Any suggestions are highly appreciated.

Thanks,

Slawek
