Purchase issues

Hello, good afternoon, I bought the same nft item 2 times in three hours but in my meta mask wallet, i have only one item in the collectable area, can someone help me to solve this issue?
Thank you in advance.

What’s the issue, exactly?
You can’t buy the same NFT twice. You will only have one token of it in collectible.
Unless you mean you bought two separate tokens that are the same copy (ERC-1155 tokens)?
