I understand what you're talking about and I got frustrated too when I first encounter this problem.
But it took a while for me to find the solution. If you're like looking for "display battlefield" button but an action is in front of it, you need to click on the button you clicked on to deselect it.
For example, if you're searching through your Card File and need to view battlefield, you can click on "your Card File" button again to deselect it, letting you view the battlefield. See the picture below.
This also applies if you're spectating a game.
