No. If the moon is already risen then the Next Set will be when it sets next and the Next Rise will be when it rises again after that.

Your image below is consistent with the table below it, noting that according to the table the moon rises at 11:48am on 2/18 and sets at 2:47am on 2/19. It then subsequently rises again at 12:35pm on 2/19. Your local time is 9pm on 2/18, at the moon info states Next Set: 2:47am (by inference: 2/19) and the Next Rise: 12:34pm (on 2/19).
