Airdrop error "This claim has not yet been created yet."

I created a claim page last week and am trying to airdrop a few to previous collectors. I enter the wallet addresses and quantity but get an error that “This claim has not yet been created yet.” But the claim page is live so I’m not sure what step I’ve missed. Any ideas?

Forgot to mention - my address is 0xa58c598a2cc0235bec70e04adfdd29cf5869a6da
