Ok, I got what it's happening, I think. There are other entries for the same product ID, and the total of them is: 36.
Do you think that deleting these, minus the last 2 ones should fix it? And also ,why could that happend?

Mmm, so something is not correct. The total units per attribute are correct (total 3), but it shows 36 in the backoffice.
