Please consider that once you work with WPBakery Page Builder you switch to a completely blank canvas to work within a custom mode.

Image galleries created with the Page Media, default titles or possible Featured Image will be not available if you work with WPBakery Page Builder in custom mode. Anyway, you can recreate any kind of galleries with WPBakery Page Builder and replace the simple native Page Media galleries end with the same layouts but with more options and flexibility.

At the same, if you have some global Theme Options settings, like custom Limit Width, these will be not taken into account to not limit the flexibility offered with the Page Builder, if you need to create a narrow column please use the column Width option, screenshot.
