I'm not sure if it's supposed to be here or in the addon forum, but since I got the addon as standerd in the new version, I'm thinking it fits here.

When I lookup Enchanting recipes I get double recipes when two people have the recipe (and since only two people have uploaded their enchanting recipes, I'm thinking if more do, I get more doubles)

First I thought it was for all the recipes, but now I see it's only for enchanting..

I did a clean upgrade.. Deleted all the files, instead of the img map and the conf..

Everything is working smooth, it's real nice! But the double thing is a bit annoying. Can this be because of a problem in the upgrade file? If so.. is there something I can do about it?

Nope, if it's a roster addon, post in the "3rd-party AddOns" forum
