Hi @adoalan ,

 

I am unable to reproduce this question for the time being. Can you provide the relevant test data and describe it so that I can answer it for you as soon as possible?

(1) How to provide sample data in the Power BI Forum - Microsoft Power BI Community


Looking forward to your reply.


Best Regards,
Henry
