Different VMtool versions on same host and both are guestToolsCurrent

When using Powercli to do some reporting on the VMtools versions I see something curious (for me)

Two machines on the SAME host have different readings for

New-VIProperty -Name ToolsVersion -ObjectType VirtualMachine -ValueFromExtensionProperty "Config.tools.ToolsVersion" -Force

New-VIProperty -Name ToolsVersionStatus -ObjectType VirtualMachine -ValueFromExtensionProperty "Guest.ToolsVersionStatus" -Force

get-vmhost -name vmXXXX.loods.local | get-vm | Select Name, Version, ToolsVersion, ToolsVersionStatus | ft

Lync2013 DIR2                                                         v9                                    9221 guestToolsCurrent

Lync2013 DIR1                                                         v9                                    8300 guestToolsCurrent

When I look in the about screen on the server itself both report 9.0.5 build 1065307. So according to the version in the about screen the versions are the same.

Please tell me , whats going on?

Best regards,

Gert
