This is odd, I have an Inna's Radiance on my monk that has both Cold resist and All Resist, however, when I try to select this on the character planner, the second affix has neither choice. It pretty much becomes one or the other.
If I were to select a white base item, and load up the affixes, the same thing happens. ONLY for the second choice. All subsequent choices show correctly.
Not sure if this was already posted, as I didn't really do an extensive search of the forums.
