Hi @Anonymous It might be due to mismatched data types or inconsistencies in the columns used for the relationship.
Could you please try these for solving

1. Match Data Types: Ensure both columns (ID and Index) have the same data type in Power Query.

2. Trim and Clean Data: Remove extra spaces using "Trim" or Text.Trim().

3. Check for Duplicates: Remove duplicates in both tables if necessary.

4. Recreate Index: Ensure index columns are correctly aligned and unique.
   After these please recreate and test the relationship in Power BI.
