ePub to mobi via KindleGen has no pop-up menu

I've just done my first conversion from ePub to mobi/azw3 with KindleGen.

Although the conversion seemed to go well when I open the mobi file on my upgraded Kindle3 I can't do the usual menu>goto>table of contents - the table of contents option is greyed out, and all I see is the beginning, end, and location options.

Is this usual for KindleGen? Is there anything I can do to get the table of contents option to show?

I've attached the original ePub file and the mobi file
