csv_post_author not getting mapped to Author

Hey all,

I just noticed that my imported posts aren’t correctly mapped to the author. When reading the post, the author’s name is correctly shown, but looking at the users overview in the backend it just shows posts:0 for every user.

The Problem is: Im trying to display a yearly overview on my archive page with wp_get_archives. With no users mapped to the posts it just shows nothing.
