Robohelp - See Also button working in WebHelp layout but not in Microsoft HTML Help layout

I have added a See Also control in one of my Robohelp topic. Added the keyword as well. When I generate this project as a WebHelp, this control works perfectly. But, when I generate as a Microsoft HTML Help and then click See Also button, I am getting the followiing message - " Selection is not associated with any topics. Please try another selection." Why is this working in one layout but not in the other? I need this control in my CHM file.

Adobe now runs Robohelp support at the link below:
