@user80 @user1023 may be able to provide some guidance for interpreting the CSV files.
As for identifying what the tags are, project-managed metadata is the best way, assuming the tags are registered to Motus. In this case, none of these match registered Motus tags. They could be real tags but not registered to Motus, or they could be noise / false detections. Noise that resembles CTT tag codes is actually pretty common, but typically the false detections are filtered out during processing.
