Hi @Merinoide ,

 

It looks like your party sort column is not in the correct data type. It is a text string instead of a number. A number column would be italicized and right aligned. Try chaging the data type in Power Query and see it goes.

The number columns below are italicized and right-aligned.

Hi @danextian thanks for your answer.

Looks like that the type of value it's not the reason

I changed this but... nothing
