Duplicating Sweeps....

I have been having an issue, and I was just curious if there is something I'm missing. I added sweeps from thecelebritycafe.com into the manual entry part of the system. They are showing in red for being duplicated and I have yet to find anywhere in the Ninja sweeps these are listed. Is the program not showing all the sweeps that are being done or do I have a glitch going on somewhere?
