Availability Group Replica name case lower

[JamesCuneo]

I am creating an availability group using

    SqlAG 'AG01'
    {
        Ensure               = 'Present'
        Name                 = 'AG01'
        InstanceName         = 'MSSQLSERVER'
        ServerName           = $Node.NodeName
        DependsOn            = '[SqlAlwaysOnService]EnableAlwaysOn', '[SqlPermission]AddNTServiceClusSvcPermissions'
        SeedingMode          = 'Automatic'
        PsDscRunAsCredential = $ActiveDirectoryAdministratorCredential
    }

I am then adding a replica using

    # Add the availability group replica to the availability group
    SqlAGReplica 'AddReplica'
    {
        Ensure                        = 'Present'
        Name                          = $Node.NodeName
        AvailabilityGroupName         = 'AG01'
        ServerName                    = $Node.NodeName
        InstanceName                  = 'MSSQLSERVER'
        PrimaryReplicaServerName      = 'SERVERNAME.Domain'
        PrimaryReplicaInstanceName    = 'MSSQLSERVER'
        ProcessOnlyOnActiveNode       = $true
        FailoverMode                  = 'Manual'
        AvailabilityMode              = 'AsynchronousCommit'
        ConnectionModeInSecondaryRole = 'AllowAllConnections'
        SeedingMode                   = 'Automatic'
        DependsOn                     = '[SqlAlwaysOnService]EnableAlwaysOn'
        PsDscRunAsCredential          = $ActiveDirectoryAdministratorCredential
    }

For some reason when the primary is created, the server name is lowercase and the secondary server name is uppercase. Has anyone else seen this? Everything is obviously working ok.
