First of all, be sure you're using 3.97a. The message is caused by Scanner's advance option "unneeded check looks for dupe sets" and simply means that clrmamepro found either a set zipfile and a set subfolder, or two set zipfiles (or subfolders) in your rompath(s). Like 'pacman.zip' in rompath 1 and another 'pacman.zip' in rompath 2. Or a 'pacman' subfolder in rompath 1 and another pacman.zip in rompath 1.

In your case it's most likely caused by existing subfolders for the cps2 chd files. As I said: Firstly update to 3.97a and recheck. There was a fixed issue for full merged sets in 3.97a.

StreetFighterZero for example: You need one sfa.zip file holding your roms (fully merged all its clones) and one sfa subfolder holding the chd. Nothing more, nothing less.

Well...of course it depends on the datfile (or direct MAME import) you're using. If the data doesn't include the cps2 chds for example but you do have them (and their belonging subfolders), the message is correct since from the datfile-side-of-view you don't need the chdfolders.
