Five admins but only I’m able to change the author

Hello,

I’m using your plugin and it works really good for me, but I have a little problem with another admins. Well, my site has five admins but only I and build in admin account are able to change the post or page authors – another person with admin permissions not (we have THE SAME role). They don’t see the “Change author” tab under the post in backend. Do you know how to resolve this? It’ll be great if every user with admin role could change the author of the post. Thank you in advance for help.
