POE2 Dupped Essence

Hi Last night I tried to sell my Greater Haste essence for 95 exalts when I put trade on currency exchange I received instantly 7exalts instead of 95 and essence was still there , I have tried to put trade with that essence in currency exchange but it said that I dont have that essence . I went to my stash tab and I have seen second in my tab . Both of them are in my stash tab , do not know if I can use them or trade them , and would apperciate if this would be investigated because nothing is worse that duppe system in game . Thanks
