Confirming Team Score of Matchs.

I would like to know, when I create a match and I put the score, it shows up the score officially but when I click on the match page, it always shows up 0 – 0 and if I try to report a score, it tells me that the other teams need to confirm the score.. but I am the admin so I want to do it myself.. how can I just create matchs that have been played on leagues and tournaments and report and accept them myself since the teams we played will not be registered on the site ?
