DSC Package resource have identical key properties

I'm trying to first uninstall a package, then install the latest version of that same package. Simple you would think, but when I include the following code in my DSC configuration:

    ### remove old product setup
    Package removeOldProduct {
        Ensure = 'Absent'
        Name = 'My Product Name'
        Path = ""
        ProductId = ""
    }
    ### now install the latest product setup
    Package productSetup {
        Ensure = 'Present'
        Name = 'My Product Name'
        Path = "$productShare\Repository\product.msi"
        ProductId = ""
        Arguments = "ACCEPT_EULA=1 /q"
        DependsOn = '[Package]MsSql'
    }

While creating the .mof file, I receive the following error:

Test-ConflictingResources : A conflict was detected between resources '[Package]productSetup and '[Package]removeOldProduct in node 'myNodeServer'. Resources have identical key properties but there are differences in the following non-key properties: 'Path;Ensure;Arguments'.

I don't want to use a Script resource to process my uninstall. What am I doing wrong here?
