How to buy same thing multiple times using In App Purchase for Android (UE4 Blueprint Project)

I want users to be able to buy same thing more then once. I have IAP in my android game and are working but after i buy one item the next time i try to buy it it says AlreadyOwned. I want to be able to buy it multiple times. I am also using Googles test IAP android.test.purchased maybe repurchase doesen’t work with that?
