dublicate token Claim page

I created a contract step by step as shown in your video tutorials, plus a token, which I minted 3 times and sent two to 2 addresses as an airdrop. After that I installed the Claim App but wasn’t able to offer the same token in that Claim page. So I created the exact same token (obviously on the same contract) and 15 people minted it. Is there a way to merge these tokens, because they show up as two items on Opensea.

Thank you very much.

kind regards

Daniel
