Issue with HubSpot to Clay Contact Data Update for LinkedIn URLs

Hii, I'm currently importing contacts from HubSpot into Clay for enrichment. However, I've encountered an issue: When a contact in HubSpot lacks a LinkedIn URL, and I subsequently add the LinkedIn URL to that contact in HubSpot, re-importing or refreshing the data in Clay doesn't update the contact's information. I've verified that auto-update is enabled at both the table and column levels in Clay. Despite this, the updated LinkedIn URL doesn't reflect in Clay after re-importing.
