sorry, you are right, there were duplicates. Problem was there were two values, one without last <Space> one with last <space>. I have found it. Interestingly in Excel and Power BI it is be used as identic value. Only powerquery knows, that therae ar two different values. Now I have deleted the last space, delted duplicates and now I can use 1:n relationship.

    Yup, I have encountered this with SQL Server, two values 'Contoso' and 'Contoso   ' are considered the same in SQL Server, but Power Query doesn't considers this so it shows both Contoso in the drop down.

    DECLARE test TABLE (Brand VARCHAR(20))
	
INSERT INTO test 
VALUES 
('Contoso'), 
('Contoso ' ), 
('Contoso    ')

SELECT DISTINCT * 
FROM test
