Accidental Duped armor through shop tab

Hello,

2 days ago or something i put a yellow armor i found in the store tab and priced it for 1x exalt.
No offers was gained so i eventually ended up changing the price of it to 2x Alchemy orb and kind of forgot about it whilst it was also not getting any offers.
This was during the times where the poe2 trading website kept going offline.

Yesterday and today i started receiving offers on the armor of 1x exalt, but i kept ignoring it because it's 1 exalt who cares im busy.
Eventually today i went to town to check on my store tab and clean it out a bit, when i noticed that the armor was in my store tab twice, once priced for 2x alchemy orb and once priced for 1x exalt orb.

i took both the armors out and put them in my 5th stash tab next to eachother so that devs can check the hardcoded values on it to confirm duplicity.

I'm not sure how to replicate this bug other than putting item in store tab, pricing it, adjusting price and being negligent with answering to offers.

The stats of the armors are identical.
Name: Plague Cloak - Advanced feathered robe
Energy shield:246
+55 to maximum energy shield
62% increased energy shield
19% cold resistance
21% lightning resistance

i have this armor 2x. identical.
