Breadcrumbs Home Page Name option is not working

I'm using RoboHelp 9 and Microsoft HTML Help is set as my Primary Layout. In the Properties dialog box for this layout, I select the "Add Breadcrumbs Links" check box. I do not have breadcrumbs in any of my master pages. I then open the Breadcrumbs Options dialog box and select "Top" from the Home Page Name drop-down list. The breadcrumbs appear correctly in the Preview window (Top > Topic1). I click OK, and then save and generate my layout. It compiles correctly, and the breadcrumbs are placed correctly and working, but instead of using "Top" as the Home Page Name that I selected, they use "Home" (Home > Topic1). What am I doing wrong? Thanks!
