To resolve this issue where Clay shows more errors than you expect, try these steps:
Clear browser cache and refresh - This can resolve persistent error messages that may be incorrectly displayed.
Use "Run All Rows that haven't run or have errors" - Right-click the column, click Play, then select "Run All Rows that haven't run or have errors" to specifically target problematic rows.
If the error count still seems incorrect after these steps, the discrepancy between your observed 40 issues and Clay's reported 300 errors may resolve once the cache is cleared and the column is properly re-run.
