Batboy - wowh, it is really great to see how much attention you put into the post. This I find the most amazing thing about Flyertalk.com, everything is so detailed and one learns things never imagined.
Yes, you are right there is a discrepancy. Actually I am allergic against any kind of walnuts, cashews are no problem and I actually enjoy eating them. But walnuts, I do not know why, are just making me lose it.

Thank you for your reply!
