Help - Excel files - row numbers being concatenated to generate false positive cc#'s or ssns

Has anyone experienced a high number of false positives found by Discover Network DLP when it crawls excel files?  It is somehow concatenating row numbers to create erroneous credit card numbers or social security numbers.  Has anyone found a way to tweak the filters or concepts to avoid generating these false positives?

You can add some proximity rules to the mix.

Hello bphang.  Thank you for your response.  I assume this would be a rule that could be added under the exceptions within the polices?  I see "template" and "keywords".  How would I include a proximity rule?
