Problem with Duplicate Disc's in multiple changers

Colby...

I have found a rather interesting behaviour...

I have 2 cdp-cx350's with around 520 cd's I have 2 pairs of CD's that are exact duplicates of each other (don't ask me why)...

I have one CD in the first player and the duplicate in the second player.

When I search for discs CDJ finds the CD in the first player and identifies it, however, when CDJ checks the second player and finds the identical disc, it does not add the disc to the second player also, it simply moves the disc from the first player to the second.

It seems as though CDJ thinks that the disc has been moved and has simply updated the database.

Is there any way to solve this problem??

Hopefully this makes sense.
