I tried to make a test case for the NaturalAttack issue and discovered the Template granted NaturalAttacks aren't even being displayed in the equipment.
PCGen 5.17.12-Dev Build 16427
New UI is displaying Purchased Equipment (not natural attacks, apparently). Does it display ANY Natural Attacks, or it this only impacting TEMPLATE based ones?
Race based and Template based are both impacted. Create a Wolf character and you'll see they don't get any attacks either... if you load a wolf character from before the New UI you'll see an error message about it as well in the console.
