Consumable Product Restore Error

I am trying to implement In App Purchase with Unity.
But i guess my issue is irrelavant to development tool.

I have created consumable product for buying coins.
And when i tried to test first it got success confirmation but no coins were added as i missed placed that code.
But after fixing that i did upload new ipa to testflight. after that when i tried to purchase coins again i got following message. which i guess shouldn't be there for consumable products.

"This In-App Purchase has already been bought. It will be restored for free."

Is there anything i misunderstood related to consumable products.



Thank you for any help in advance.
