Unidentified contract: how to add name?

Hi, my Manifold contract attached to the minted NFT is showing as ‘unidentified contract’ on Opensea. I already named the contract in Manifold when it was created, however the name is not showing on the OS page. How can I fix this please / add a name? Thank you!

OS page: https://opensea.io/assets/ethereum/0x9dbc07f98bbe292d50b4c7e94547ffc070b1805d/1

My wallet address: 0x24A0435DD391A6962d8d99CE19f51f2b540412b5

Manifold claim page: GEISH4
