Unable to choose author in custom post type

[danielpataki]

I'm not sure this is a bug, I may not be familiar enough with the functions governing this in WP.

The problem is that I can not choose an author for custom post type posts. If I go to the normal posts, the list is populated with about 20 names.

In custom post types, I can not choose any author, the currently logged in user is shown for new posts, and only the original author is shown for already created posts. I can not change the author of already created posts, even if I am logged in with a different user (who is an admin).

I am guessing this has to do with permission issues, but I looked at the register_post_type() function and also at the code in the core which registers the basic types like post and page and I couldn't find any arguments which would resolve this.

Can confirm it.
If I use the functions from ​WP Enginner I can choose the author if I'm the network admin, but not if I'm the admin/blog owner.
