When I out on 2 pieces of the Grunil Armor it’s supposed to trigger ‘All AP +5”

On the Inventory sheet where you out on your armor, the AP number doesn’t update to show the additional 5 AP.

Am i missing something?

The AP buff from Grunil is "hidden" AP and doesn't apply to your gearscore. You still get the buff you just won't see your AP increase. I don't know why it works like that but it does.

Yup. Exactly how it works.

You got whats called hidden stats. You still get the bonus tho.
