power bI is duplicating rows after loading data from power query to desktop

I have noticed that after combining 10 csv files in power query and performing rename, delimiter, sorting functions, when I closed and applied the transformation , the power BI desktop has twice as many rows.

Can someone help me as to where i could have made a mistake or overlooked?

@charanrazzz , Without looking at the steps, it's difficult to tell, but I suspect you might have appended the tables twice.

 

If this does not help
Can you share a sample pbix after removing sensitive data.

Hi, @charanrazzz 

Thanks for amitchandak reply. You can use third-party tools to share your pbix files (Google Drive, OneDrive, etc.), and remember to set public access when you do so.

Here are some notes:
If you are unsure how to upload data please refer to https://community.fabric.microsoft.com/t5/Community-Blog/How-to-provide-sample-data-in-the-Power-BI-...

Please show the expected outcome based on the sample data you provided.

I'm practicing with a open source data. So I dont mind sharing the complete file. I have intially combined all 10 csv sheets, so im not sure where it could happen as i dont remember selecting anything as such to append. How do i share the pbix file?
