My menu looks beautiful when I'm editing it. All my graphical and text elements fit neatly onto the slide, without any stuff hanging over the margins. When I preview, it adds white space on either side of content area for some reason. I have checked everything. Now it appears that as long as I have some type of player navigation on the bottom (Prev, Next, seekbar), it will appear correctly. This makes no sense on a title side that doesn't need navigation or audio. This is the only slide that has this problem. I am using the same slide master as the other slides (in fact I've checked every single slide master.)
I'm hoping this is something dumb I've done. Please see attached. Thanks!
