How does 721 token numbering work in the Claim Page app if there are already tokens minted

I have a Manifold Studio ERC721 contract deployed that already has 21 tokens minted on it with tokenID’s 1-21
If I now create a claim page for edition #22 and set the Token Supply to 1 will it be assigned the correct tokenID (22) once someone mints it?
And am I correct to assume I can repeat that process for edition #23 but only after edition #22 has been minted (it doesn’t look like there’s a way to set up all the editions and mint them in order)?
