Color Name not recognised in Color Label Macro in 2021

Hi. I have been using X7 for years, utilising a macro found on this forum to label my colors in a spec sheet for my artwork.

We have recently decided to upgrade to 2021. 

The color label macro no longer recognises color names from my custom color palettes. It produces "unnamed color" instead.

If I run the macro on a color from a default palette such as Pantone+ Uncoated, as an example, the macro does recognises the color name.

If I run the stock ColorChartCreator macro on my custom palette, it does recognise the color names.

I am not sure with the 2021 update whether there is a compatibility issue with the label in the macro, the macro itself or the color palette.

I have included the code below. If anyone has experienced and solved I would greatly appreciate it.

Sub LabelSwatches()
  Dim sr As ShapeRange, sh As Shape, cn As Shape, col As Color
  ActiveDocument.Unit = cdrInch
  Set sr = ActiveSelectionRange
  If sr.Count = 0 Then MsgBox "Nothing selected!": Exit Sub
    ActiveDocument.BeginCommandGroup "ColorsNames"
      For Each sh In sr
       Set col = sh.Fill.UniformColor
       Set cn = ActiveDocument.ActiveLayer.CreateArtisticText(sh.CenterX, sh.CenterY + (sh.SizeHeight / 2.5), col.Name & vbCr & col.Name(True), cdrEnglishUS, , "Arial", sh.SizeWidth / 0.18, , , , cdrCenterAlignment)
       cn.Fill.ApplyUniformFill CreateCMYKColor(0, 0, 0, 0)
     Next sh
End Sub
