Updating CRM Import Data in Clay After Domain Changes

Hello, I have a question about Importing from a CRM. I have a Segment companies in HubSpot with no domain. I used Clay to successfully pull domains for about half of them and export back to HS. Now the Segment is half the original size. How do I go about updating the table in Clay? Clay is still showing all the companies in the original segment, even half now have domains.
