Double counting error of packaging for ecoscore

Ive noticed that some canned products double count the carbon emissions of packaging. For example, this product of canned sardines: Sardines au piment d'Espelette - Phare d'Eckmuhl - 135 g vs this one: Sardines - Deep cove - 125 g. The first can lists the product under raw sardines for the life cycle analysis. and the second under canned sardines. Meaning that the second product counts the emissions from the packaging twice. So, how do i change the life cycle analysis category to prevent this error?
