Export csv column names different from the list

Hi there.

I got a list with some columns. When exporting to CSV it gives me the old names of the columns.

They were edit and it was put a new name. When I see online all is fine but when exporting to CSV it shows the old name.

I'm having some difficult trying to solve this issue.

Can any help give me some pointers?

Thank you.
