I would have checked the log file for all of this. Ultimately, the game operates not according to the rulebook but according to the code.Where do you see the list of weapon traits, and where does it tell you that enhancements are the same as cold iron? I see nothing about it in the encyclopedia.
Also, does adamantine affect DR/Cold Iron, or does it only affect DR/Adamantine?
Find a +3 enhanced weapon (does this even exist in Act 1?) and see if it works as it should.
