No, you have Resist 1 twice, when you can only use ot once. Same way that several things give Threats Lycanthrophy 1, but the Mooncalved Mutation specifically give Lycanthrophy +1.
This is true. If we ever want to increase your skill, we'll say something like "Gain Resist 1; if you have Resist, increase your Resist by 1." (Spoiler: We want to.)
