VBA Excel ListView Checkboxes do not show in Userform

I have a UserForm with a MultipageControl (name Controller_MultiPage). At runtime my code adds pages to the Multipage and creates a newListView on each page. Every ListView has:

      With newListView
        .MultiSelect = False
        .Width = Controller_MultiPage.Width - 10
        .Height = Controller_MultiPage.Height - 20
        .View = lvwReport
        .HideColumnHeaders = False
        .ColumnHeaders.Add Text:="Signal Name", Width:=.Width / 10 * 4
        .ColumnHeaders.Add Text:="Type", Width:=.Width / 10
        .ColumnHeaders.Add Text:="I/O", Width:=.Width / 10
        .ColumnHeaders.Add Text:="Description", Width:=.Width / 10 * 4
        .CheckBoxes = True
        .FullRowSelect = True
    End With

then I populate the newListView with data from an XML file:

         For Each node In list
            With node.Attributes
                Set listItem = newListView.ListItems.Add(Text:=.getNamedItem("Name").Text)
                listItem.ListSubItems.Add = .getNamedItem("Type").Text
                listItem.ListSubItems.Add = IIf(.getNamedItem("Input").Text = "1", "IN", "OUT")
                listItem.ListSubItems.Add = .getNamedItem("Description").Text
                listItem.Checked = False
            End With
        Next

but the checkboxes do not show. I can see the space for them in front of the first column and by clicking that space the checkbox of that particular row then appears. What I also noticed is that if I change the property

listItem.Checked = True

the behavior described above does not change, and when I click the free space in front of the first column (checkboxes space) the chsckbox that then shows up is still unchecked. Any idea?
