CVS Columns Combined After PowerBi

Hey Microsoft, just gotta say, this is my second time writing this.  I created a new post without any notice of having to login or register.  Click post, and then I'm prompted to login or register.  I registered and was sent to the forum homepage and my post is gone! Why?

Anyway, with much frustration, I'll rewrite everything.  If you read this and it seems short or, I'm sorry, explaining something twice is never fun.  

I imported (get data) a CVS from Powerbi desktop, Windows7.  After saving the pbix file, my original CSV file is edited.  All my columns are combined into one.  Why did Powerbi change my file? How do I get it back? See file and captions below.

When I opened in Bi, I selected "Edit" and "Set First Row as Headers" (because Column1, Colunm2, does nothing for me), and deleted the first row.  Did this change my file?

Thank you.
