It seems like the manual rain gauge is showing wrong, So the issue is no more! I got this results by using a bottle were the area is the same as the rain gauge area, filled it with 5mm water and poured it into the rain gauge. The result in WU was 4,4mm, then I poured the same amount in the manual gauge and got 8mm on that gauge. The measurements aren't precise but I guess that it's proved that the manual gauge is not very accurate.
