<$pageGroupParentTitle> and <$pageGroupTitle> not working

Hi there! I’m trying to add the chapter name in the header on my compile draft. However whenever I use these placeholders, I don’t actually get the title I’m looking for… just the place holders as actual text. The attached screen shot has my compile settings.

Any assistance would be most appreciated.

Thanks!

It works in Scrivener 3 (Windows) at my machine.
