Element Style: Margin-Left 168

I have looked at every line of the CSS of this plugin and apparently have missed where this is pulling from.

My website:

You can see how the picture is inset 168px. Firefox just shows this as “element style”.

Anyone know how I can get rid of this. 6 hours of fidgeting with this has made me bonkers.
Thanks for your help!
