Change Mob Drops Problem

Hey guys, once again its me to ask for your help :D

so for my server i wanted to change the Items that Demon Shaitan drops (will be d9 server)
so i went to _RefDropClassSel_Equip and changed the Drops from lv 90 mobs from ProbGroup28 (which was obviously D10 Items) to ProbGroup27. But it still drops D10 Items. i also changed it once to ProbGroup26 (which is the second Equip of the 9th Degree) for test. Well from then it didnt drop the 3rd Equip anymore but it still dropping D10 Items.

If anyone out there could help it would be rly awesome =)

Thanks. :)
