Items added in TOC when compile Winhelp 4

Hello all,

I've set a TOC by this way:

I use robohelp 9 with last patches set.

As you can see super_toto!!! book is empty.

But when I compile in Winhelp 4, I've got those results:

I've got now a super_toto!!! book not empty any more with craps in it... Those craps have names which are part of existing entries in my toc...

I've tried to delete the book but without success. I've tried to delete the associated entries of the craps, but, other craps are generated.

Have you got an idea?

Thanks.

  Philippe.
