When running QA (quality assurance) reports, you will encounter false positives. They are correct segments wrongly flagged as errors.
Example:
Source (en-GB): Could we meet on 3/4/2017 at 2:30pm?
Target (fr-FR): Est-ce qu’on peut se rencontrer le 3 avril 2017 à 14h30?
Number ‘4’ is missing from the target, so that would be marked as an error – however we know the date is correctly localized, so that’s a false positive.
You can find this example and some more information on the topic in this article.
