I am the primary user, and I have set up custom field view in the layout. It all works fine for me.

 

But when secondary user signs in, they see the general layout, not customised view.  Even if they go to "setup" and check the layout there, it comes up like I have set it up, but when you go back to viewing Leads, the fields are still not displayed as per this custom setup...

 

Is there somewhere I should be clicking on to ensure this happens or is it a glitch?
