Nested Display Posts Shortcodes dosen’t show Tiny Slider Element

Hi Mr. Bill Erickson (or however is reading),

first of all: I love the PlugIn.
It is so slim and still so powerful!

For our (unofficial) University Website i am building some nested Elements.
Sadly i reached a situation, where i got a problem with the »include_content=”true”«. In the first »Parent-Page« the implemented Tiny Slider from the »Child-Pages« works fine, but the second spanning Page does not display the Slider anymore. Is this a Shortcode Nesting Problem? Do you have any Idea, what i can do?

Thank you so much in advance! =)
Best,
Marius
