Question about having 2x Agility Rings of similar specs

Will 2x Agility rings scale together or will only one specific stat be prioritized?

Wondering if I am wasting a ring slot having 2x Agility rings with differing stats or if they are combined. (The stats are small enough where its hard to tell)

Edit - looking at other topics it would seem it’s either by design or a bug that some rings do not stack effects or are missing desired results.

You are actually wasting TWO ring slots because neither of those rings work
