RH11: Assigned Map IDs Issue

I inherited an Online Help system and have had to make many updates - including renaming topics to more logical names. But when I go into a topic's properties, often times there is more than one topic name in the Assigned Map IDs field. But, no matter how I try, I cannot get rid of the extra topic name that does not belong there.

I've even tried manually editing the BSSCDefault.H and whcshdata.js files, but the topic name does not appear in either file. Where does RH get these topic names if not from these two files?

Thanks.
