how to get the number of levels in SlideMaster correctly

(PowerPoint 2019)
There are 9 levels in SlideMaster but the code below print only just 5.
what is the problem?

ActivePresentation.Designs(1).SlideMaster.TextStyles(ppDefaultStyle).Levels .Count

In modern versions (later than 2003) just count the paragraphs in the text placeholder (normally shape 2)
ActivePresentation.designs(1).SlideMaster.Shapes(2).TextFrame2.TextRange.Pa ragraphs.Count

Thank you so much for your perfect reply
