If your lookup between tables isn't working, try these troubleshooting steps:
Force Rerun the Column: Click the column header and select Force Rerun Column to reset it.
Delete and Recreate: If the issue persists, delete the affected column and create a fresh one, then re-map your data.
Check Column Configuration: Ensure your Target Column, Filter Operator, and Row Value are correctly configured. The lookup can only filter using one column at a time.
Note: Make sure "normalisedurl" is spelled correctly in your column name and that both tables contain the data you're trying to match.
Make sure both columns are run through the Normalised URL enrichment first so they’re in the exact same format (https/http, no trailing slashes). Also confirm there are no hidden spaces. Once both are normalized, the lookup should work.
