If you file a dispute with one CRA, the creditor can choose to simply delete the contested reporting without any positive verification or correction, but without any express statemnt that they find the reporting unverified or inaccurate. Deletion will dismiss the dispute. That alone does not require that they delete with other CRAs.
Deletion with other CRAs would only be mandated if they positively concur that the reporting cannot be verified or corrected.
FCRA 611(a)(7)(E)(4) states that:
"if the investigation finds that the information reported was inaccurate, promptly notify each consumer reporting agency to which the person furnished the inaccurate information of that determination and provide to the agency any correction to that information that is necessary to make the information provided by the person accurate. "
Since the results of the TU dispute only notify that the reporting was deleted, and not that it was found to be inaccurate, then the creditor had no requirment to report the same deletion to any other CRA. They may have chosen, for example, to simplify their reporting by removing it from one CRA.
Additionally, any deletion based on a dispute only appplies to the information disputed, and thus dispute of a late payment would not have required any deletion of the entire account. Thus, even if they had concurred that the reported lates were clearly inaccurate and thus must be removed, deletion of the entire account was voluntary, and not required by the dispute. Thus, no deletion of the account with any other CRA would be at issue.
If you wish to receive a determination as to the accuracy of reporting with the other CRAs, you must file a separate dispute with each and receive the results.
