Duplicated offers in the list
In my analysis, this is the root cause of this IREQ. When the user clicks on the second offer in the list, our logic is not prepared to handle a duplicate offer. Talking with Lopes da Costa, Valentina , we understand the following:
If the user redeems an offer and doesn’t use it, he should not be able to redeem the same offer again until he uses the already-redeemed one!
This will solve these duplication entries and also solve the bug at the same time!
When we developed the Promo code at checkout page X config offer type feature, I also added this functionality at the checkout. As the user is not seeing the offer list we should prevent duplication there. With this proposal we’ll keep the same behavior and consistency

PS: I tested, and this will not happen if the user changes between two different offers and then applies one or the other in sequence.
Proposal of solution
Option 1: Validate if the promo code was already redeemed and throw error
