Leaf Armor conflicting stats in two books

[Major Doom]

I was looking through Pathfinder Chronicles: Campaign Setting and Pathfinder Campaign Setting: The Inner Sea World Guide and noticed that each has conflicting information about Leaf Armor.

From Pathfinder Chronicles: Campaign Setting
Cost: 500 gp
Armor Bonus: +3
Maximum Dex Bonus: +8
Armor Check Penalty: 0
Arcane Spell Failure Chance: 10%
Speed (30 ft.): 30 ft.
Speed (20 ft.): 20 ft.
Weight: 10 lbs.

From Pathfinder Campaign Setting: The Inner Sea World Guide
Cost: 500 gp
Armor Bonus: +3
Maximum Dex Bonus: +5
Armor Check Penalty: 0
Arcane Spell Failure Chance: 15%
Speed (30 ft.): 30 ft.
Speed (20 ft.): 20 ft.
Weight: 20 lbs.

I boldfaced the stats that are conflicting. I have seen a few threads claiming that Leaf Armor has the same stats as Studded Leather, but I can't see how that is correct, when Leaf Armor was made by "secret alchemical compounds to treat special leaves", compared to Studded Leather being made up of leather and metal studs. More specifically, leaves weigh less than leather with metal studs.

So which one is correct?

The Inner Sea World Guide is a Pathfinder rules update for the previous campaign setting book, written for 3.5. Unless there is a very, very good reason to do otherwise, I would assume that anything in the ISWG supersedes its predecessor.

Yup. ISWG is PFRPG. Use the updated stats. There are several pathfinder products that were released under 3.5 rules that don't really fit with PFRPG. In the case of the campaign setting, it's best to ignore it.

Armor Bonus: +3
Maximum Dex Bonus: +8 is wrong.

The design of the system puts limits on the AC obtained, and that item breaks those design limits. Nothing is supposed to exceed +10 between AC and Dex.
