slider font sizes not working

I am using LayerSlider 3 by codecanyon.

I put up the sample slider they offer just to try, but I noticed that the fonts show up really small on my website. In the slider preview everything seems okay, but on the actual site all the words are tiny.

The style codes seem to be working, because the color and shadows are correct. But the pixel size in the code does not seem to work.

Im just trying to learn, any help would be appreciated.

Thanks!
