Burn token to start over, help!

Hello, I’m so confused - I wanted to create a multiple editon piece to show on Foundation, so I created a contract ( ERC1155 ) and minted a 50 edition piece, but it didn’t show up on Foundation, so I wanted to burn it to try again, which I did via etherscan. However, it’s still showing on my contract? I just want to start everything over. No idea what to do…

My wallet: 0x26295e1F880190f92563551bf1E14D567b941c56
Contract: 0x44B91Ae8Dc380DF75485A07C6Af6E82D7590Fb08

A burned will will still show in Manifold. You can request Opensea to hide it~
