edit tournament point bug

Hi
Us Team play vs Irf Team – us won irf lose –
I insert point and the total point on torunament table show US 3 POINT, IRF 0 POINT

Than was a mixtake, US and IRF won, so i edit match result and
the total point on torunament table show US 4 POINT , IRF 1 POINT instead of US 0 and IRF 3.

i change again and insert US won IRF Lose but the table scho always US 4 POINT IRF 1 point.

It didnt delete the old result, but just add the point….. like 2 match in 1….
i checked every match, but IRF and US teams play just 1 match….
I need to insert back right point ( US 3 , IRF 0 )

Where can i remove the total point? if i edit match again, maybe put more point on the tournament point table…
Thanks
