Sounds like bcl2fastq experienced a software issue. I suggest that you re-run the demultiplexing. I have seen this posted rarely and if I recall had experienced it one time. bcl2fastq re-run fixed the problem.

I will also put a plug in for clumpify.sh from BBMap suite. It allows detection of all/optical dups without alignment of data.
