This means that the claim is no longer subject to review. Claims may be withdrawn at the request of counsel or by the Trust. The reason for withdrawal is displayed on the Review tab:

Most Trusts will withdraw a claim if the response to a deficiency or offer is not received within 180 days from the date of notification. For more information about the deadline policy of a particular trust, please see the relevant section of the TDP and other notices available on the individual trust websites.
A withdrawn claim may be re-filed at any time. The new claim will be assigned a new place in the FIFO processing queue based upon the date of re-filing, but the claim will retain the date of the original filing for Statute of Limitations assessment.
HK Porter will reject a claim if a timely response is not received. Rejection is simply withdrawal of the claim on behalf of the trust. Claims that are rejected by HK Porter will not retain their original filing date for purposes of Statute of Limitations assessment and a fee of $35 will be imposed for their re-filing.
The Garlock Trust will not permit the re-filing of a claim that is Withdrawn by Counsel.
