App-V 5.0 SP2 - PackageID & VersionID

Question

I use PowerShell for testing newly sequenced applications. It's very basic with add and publish ... then unpublish and remove for cleanup.  In general my PS script is:
# First code adds the package
clear
$pkgPath = "\\svr\path" + "\"
$pkgAppV = $pkgPath + "AppName.appv"
$pkgXML = $pkgPath + "AppName_DeploymentConfig.xml"
Add-AppvClientPackage -Path $pkgAppV -DynamicDeploymentConfiguration $pkgXML | Publish-AppvClientPackage
# Next code removes the package
$pkgName = Get-AppvClientPackage -Name *AppName*
Unpublish-AppvClientPackage -PackageID $pkgName.PackageId -VersionID $pkgName.VersionId
Remove-AppvClientPackage -PackageID $pkgName.PackageId -VersionID $pkgName.VersionId
This works fine with applications sequenced with App-V 5.0 SP1, but not all packages sequenced with SP2.  What I've found is that there are duplicate or multiple entries for the properties of the package.  For example,
if I do $pkgName.PackageID, there are 2 GUIDs.
Example with SP1:
$pkgName = Get-AppvClientPackage -Name crystal*
write-host $pkgName.Name
write-host $pkgName.PackageId
write-host $pkgName.VersionID

Example with SP2:

write-host $pkgName.Name
write-host $pkgName.PackageId
write-host $pkgName.VersionID

See the additional entries?  Is this a bug?

With your tip and finding an example of handling an PowerShell array/collection, I've found the following works better now for my cleanup script and will handle multiple apps of the same name.
foreach ($pkgName in Get-AppvClientPackage -Name *AppName*) {
    write-host $pkgName.Name
    Unpublish-AppvClientPackage -Name $pkgName.Name
    Remove-AppvClientPackage -Name $pkgName.Name
