Normally this shouldn't happen. When your search request fits both files and they are both exactly the same size Xolox normally automatically assumes that they are in fact the same file and will only display one of the two (the one it found first).

This could only happen if you made two different search requests and selected one file in each. Which would be unnecessary, since Xolox will see that the new file does fit your search terms AND is the same size ...

The Seeker had some very extensive descriptions about this. Maybe you should look them up.
