I have found a database with those discounts, i just need to migrate this ... migrating from 1. to 1.7 has been a real pain, with information just disappearing, i now just need to solve this part of group discounts ... hope it is a bit clearer .... already migratin from 1.6.11 to 1.6.1.24 made that info disappear, but it is somewhere in the database as discounts are applied properly, it is only that they are not listed.
On the screenshot below, this group has discounts applied, but they are not listed, that is what I am trying to work out
