Ok, I think I found it. Problem is, that you have multiple disk indicators in your filenames.
RCB uses the disk indicator to make game names unique and to detect multi disk games. If a rom file is detected as the 2nd, 3rd or whatever disk of a game then RCB just adds this file as additional rom file to an existing game (imported with the first disk). So, in your scenario the disk indicator is correct and it strips the "_disk2" away. But it still has (Disc 2 of 4) in the name, so RCB thinks this is a unique game and tries to scrape data for this game separately.
To strip all disc specific information, you should use "\(Disc .*\)" as disk indicator. But you have to rescrape this game to get the additional discs into the database.
