Claim page open edition on 721s

I wanted to do a claim page open edition of 721s but I wanted the title to say
Title of art #1, Title of art #2 and so on.
But it is putting “Title of art #4/100”
Now the open edition has expired and only 4 were minted. But the titles say there are 100 tokens.
Can this be changed so the titles say what I want? I would have set it to unlimited but it says it does not put a number on it at all. I guess I should have tested this on testnet. Do the claim pages work on testnet?

How do I fix this. I tried to edit the metadata file and upload to arweave but It is not letting me to set the new TokenURI.
