[Plugin: Theme Blvd Responsive Google Maps] Not Responsive in Akita Theme

I have the plugin installed in your Akita Theme and working on the following page, but it doesn’t seem to be responsive. The shortcode resides on a page titled “Google Map” and that page is in page builder as 50% column item.

Here is the shortcode I’m using:
[tb_google_map address="191 Kingwood Avenue Northwest, Salem, Oregon" zoom="19" maptype="hybrid" width="436px" height="500px"]

If I remove width="436px" or change it to width="100%" the map appears as a 1 pixel wide map. Do you have any ideas of what I’m doing wrong?

Thank you,
Paul Bryant
