Oh sorry, of course this post was meant to go to the bug report, I don't know what I did.
Here is my Rates.ini

I guess you are refering to this section:
# Maximum drop occurrences.
# Note: Items that have 100% drop chance without server rate multipliers
# are not counted by this value. They will drop as extra drops.
DropMaxOccurrencesNormal = 2
DropMaxOccurrencesRaidboss = 7
Should I try to set DropMaxOccurrencesNormal to something greater ? To be fair, I'm not 100% sure that Adenas don't drop only when Monster drop already 2 items.
