My Lightroom 5 Brightness and Fill light sliders and buttons disappear and reappear all the time. I don't ever know how to get it back. Even with restarting the program. It just disappears. (I'm updated to the latest version.) I have posted this before but the way this forum is setup there is no easy way to find my previous posts. I have no easy way to find if there is a solution or response from Adobe. I wish Adobe would just email me or if there way to speak with someone.
