Bug? Typo in NB6 class causing erroneous channel name

Public Sub Initialize (ChannelId As String, ChannelName As Object, ImportanceLevel As String) As NB6
    ctxt.InitializeContext
    PendingIntentStatic.InitializeStatic("android.app.PendingIntent")
    NotificationStatic.InitializeStatic("android.app.Notification")
    common.InitializeStatic("anywheresoftware.b4a.keywords.Common")
    Dim jo As JavaObject
    SdkLevel = jo.InitializeStatic("android.os.Build$VERSION").GetField("SDK_INT")
    If SdkLevel < 23 Then
        SupportLevel = S_OLD
    Else if SdkLevel >= 26 Then
        SupportLevel = S_CHANNEL
    Else
        SupportLevel = S_BUILDER
    End If
    If IsOld Then
        OldNotification.Initialize
        OldNotification.Icon = "icon"
    Else if IsChannel Then
        ChannelId = ChannelId & "_" & ImportanceLevel
        NotificationBuilder.InitializeNewInstance("android.app.Notification$Builder", Array(ctxt, ChannelId))
        Dim im As Map = CreateMap("MIN": 1, "LOW": 2, "DEFAULT": 3, "HIGH": 4)
        Dim i As Int = im.Get(ImportanceLevel)
        Channel.InitializeNewInstance("android.app.NotificationChannel", Array(ChannelId, Application.LabelName, i))
    Else
        NotificationBuilder.InitializeNewInstance("android.app.Notification$Builder", Array(ctxt))
        Dim pm As Map = CreateMap("MIN": -2, "LOW": -1, "DEFAULT": 0, "HIGH": 1)
        Dim p As Int = pm.Get(ImportanceLevel)
        NotificationBuilder.RunMethod("setPriority", Array(p))
    End If
    If ImportanceLevel = "DEFAULT" Or ImportanceLevel = "HIGH" Then
        SetDefaults(True, True, True)
    Else
        SetDefaults(False, True, True)
    End If
    Return Me
End Sub
