Revolution Slider Navigation Elements

I’m having some issues with the Revolution Slider when testing Aqua for WordPress across browsers. Everything’s working fine in IE and Firefox, but in both Google Chrome (version 24) and Safari (versions 5 and 6), when I preview the home page the slider navigation elements are out of place. I only see the right-pointing arrow, which appears at the top center of the slider, and bleeds up into the whitespace above the slider. And the navigation buttons are at the bottom left of the slider, bleeding off the slider as well.

The only slider code I have on the homepage is the basic short code [rev_slider slider1]. I changed the slider size from 940×400 to 940×350, and have been building the slide background images at those new dimensions. I’ve tested some other slider setting changes to see if it fixes the issue, but no luck. Any ideas?

Thanks!
