Offset copy on preview only?

Hi, I have several slides in my responsive module where the copy appears correctly in Captivate – but when I export it for preview the copy is offset to the left of the canvas – see images. I can’t find any reason why this would be happening. Any ideas? The three images show the captivate art, and two different preview sizes. Thanks in advance for any help.

Font usage for online module

Am I restricted to websafe fonts or will fonts from Adobe Typekit ’embed’ into the module?
