It’s driving me crazy.. do act 2/5 Ancient Vows quests stack? I

So my normal ancient vows quest bugged. Couldn’t put relics in shrine in act 2. So when I got to act 4 I tossed them on ground. Act 5 I found the relics and was able to put in shrine and choose my reward.

Now I don’t have the relics for act 2/normal Ancient vows… and it’s driving me crazy knowing I might be missing out on a passive buff to my character.

Any advice? Do they stay or does only one quest reward work? Is there away to abandon Ancient vows and redo the quest in act 2?

Any advice?

Thanks
