Just installed wpmu google-maps plugin

When entering content into page or post, the globe icon is displayed as it should.

However, when using the Visual Composer for WordPress plugin from wpBakery, in effect, a third-party "editor", the globe-icon for inserting an existing or new map is not displayed.

Further testing determined that a 'map' shortcode, created via standard editor, and then pasted into the editing box of Visual Composer, did indeed work, and resulted in a map being displayed with viewing of post.

Is this a ‘known’ plug-in incompatibility issue?

Thanks in advance for insight.
