Duplicate Column Name in table error without any duplicate names

Hi,  amarlian 

Your solution is great iluvaccounting1  . After my testing, this bug does exist in the new version.

You can avoid this problem by clicking on these columns carefully. In addition, you can download an older version of Power BI to use.
