Cannot buy Zeta replicas if original relic is discarded

Date & Time: 25.12.2023 20:39LT
Frequency: Once (Did not reproduce)
World name: Lich
Character name: Batti Debris
NPC name: Drake <Replica Vendor>
Class/Level: MNK/90 (Probably Any/50+)
In-game time: 19:39ST
Area and coordinates: North Shroud ( 30.3 , 20.0 )
Steps:
1. Complete a Zodiac Weapon Zeta
2. Discard the completed Zodiac Weapon Zeta
3. Talk with Drake <Replica Vendor>, select "Zodiac Weapon Zeta Replication"
4. The discarded Zodiac Weapon Zeta won't be available for selection

That's how Zeta relics are designed. You either keep them if you need to buy replicas later, or you convert the weapons in the first step of the HW relics to permanently unlock the replicas.

Even if it is how the Zeta relics are designed, it feels like an unintended consequence that you lose all access to replicas if you discard the weapon (even if the exchange for the HW relic materials is intended), especially when it doesn't happen for every other expension's relic. Seems like a long-time oversight for me tbh.
