Centering text issue with LayerSlider on mobile devices

Hi,
I’m trying to center text horizontally in a slide. It works fine on large screens but when I view it on a mobile device and the text needs to word-wrap, the text starts off misaligned and then after 5 or 6 slider cycles it straightens itself out. Very strange!

Here’s a link to a sample page with the issue.

Here’s a link to a before and after screen shot of the misalignment.

Here’s a link to a screenshot of the settings for that line in the slide.

Any insight is greatly appreciated!
Thanks!
