The ring of protection is equipped but not attuned, so its bonus is not being added. Hence the AC 15 we're seeing is accounting for the armor and the DEX, but not the ring, but (to its mind) this is correct. Just check the box next to the ring at the bottom of the inventory tab in the attunement section, and you should be good to go.
The Breastplate should be 14+dex (max 2). But on my character https://www.dndbeyond.com/profile/Tyson_NW/characters/62634829 it is giving a flat 14 ac.
Its 15 to me.
Ah its supposed to be 16? Right? Ring of Protection, for now edit the Ac manually by clicking on it.
