Layerslider video issue

Hi there!  I have a licensed version of the Creativ theme.  However, I am having an issue with the Layerslider module.  When I add a video to the module, the size of the video is not correct.  I am setting the width and height of the embedded video as 600x400 but the iframe style is overriding and I can't figure out how to fix it.  As you can see, the iframe style is set as 300x150 and is not being overridden by my custom size.

<iframe style="display: block; width: 300px; height: 150px; transform-style: preserve-3d; z-index: 0; visibility: inherit; opacity: 1; transform: matrix(1, 0, 0, 1, 0, 0);" src="https://www.youtube.com/embed/7ViLvXSWtbM?enablejsapi=1&amp;html5=1&amp…" width="600" height="400" id="iframe72720" class="HasListener"></iframe>
