Nope, that should do it!
What I was somewhat expecting to see was that you had another folder inside the Topics folder that was named Topics. So there's definitely something amiss here.
I might suggest you try creating a new Single Source Layout. If you aren't familiar with that process, I believe I have a video that will show you how to accomplish it.
Once you add a fresh layout, generate and see if the problem persists.
Your response prompted me to look at the WebHelp SSL properties where I found that the path to the output folder contained an extra '\Topics' folder in the string. Removed that, saved and regenerated but got the same results as the initial problem.
Deleted the WebHelp folder from the SSL folder and regenerated. The extra 'topics' folder did not appear.
I think the key was a combination of the two actions above.
Appreciated your help. Thanks
