Your tracks are listed as available to license to LabelWorx because you signed and returned the optional Appendix C on your LabelWorx contract.
If you would like to stop LabelWorx using specific releases then on your release page please ensure that LW Licensing Usage on the left is set to Not Available.
If you would like to permanently opt-out of this service, please contact us via our Request Form.
