Hi @OY 

Whether the columns in your list have changed, the problem shown here is that the columns you use union should be inconsistent, you can go to see the data in the list, or you can refer to the following link:

 Union thinks column numbers are different - Microsoft Power BI Community

Solved: UNION Query in Power Query Editor - Microsoft Power BI Community

Hi,
How do I know which data the error refers to?
Is there a way to know which query is meant exactly?
