PresentationFactory().GetPresentationText() Method Does Not Return Text from Group Shapes

I am trying to extract text from slides using below code. It does not seem to extract text from group shapes. I have attached file I am facing issue with.
SingleSlide.7z (32.7 KB)

IPresentationText text = new PresentationFactory().GetPresentationText(stream, TextExtractionArrangingMode.Arranged);
foreach (var slide in text.SlidesText)
{
    result += result + slide.Text;
}

what am I missing?
