Hi Jds, and welcome to the site.
Unfortunately, there's no way to cancel the score after you saw it. The only opportunity was _before_ you saw the score on the GMAT test. Since you know your score it means it was displayed and thus, it will be reported to all schools you listed. Nothing can be done here.
Moreover, if you decide to retake and send the new scores at some time in the future, the schools will see the scores for _all_ your previous attempts within the last 5 years...
