Unable to Publish Claim Page, Publish button is disabled

Hi all, I want to create a test claim page and upload the artwork and the list of eligible addresses. Though I am stuck on the preview page, the Publish button shown in the image is inactive, and I cannot proceed forward. I am able to click on “previous” but can’t go forward. have Any troubleshooting steps?

the issue comes when I am trying to upload a csv file of eligible addresses, If I select claim is open for everyone then the publish button works. But I need to do it for certain addresses only, and that’s where the issue is.
