After accessing my HTML Help files from an application, the text "Empty Chapter" appears in the Help tab. (See the attached screen shot.)
The Help is built by linking FrameMaker 11 files to RoboHelp 10.
"Empty Chapter" does not appear in the original FrameMaker files, nor in the RoboHelp files: I checked both the WISIWIG and HTML views. As well, the correct text appears in the <title> tag.
The app calls the Help content through context IDs.
