Images Styling – Vantage..PageBuilder

I am finding images I insert using Page Builder are adding a 3D/drop shadow effect. Where can I adjust this in the styles? I’m also getting inconsistent results.

The image on the frontend that is in the TinyMCE widget (black box image) has the shadow, the one in the Image(PB) widget (red trucks) does not.
Frontend: http://gpstrackzone.com/zone/products/

Another frontend – all of these show the shadow (Tracking Pages graphic) but on the backend the 1st and 3rd are in TinyMCE widgets and the 2nd is in an Image (PB) widget.
