Unfortunately I’m not familiar with the Revolution Slider or the Essential Grid plugin. Have you tried contacting the developers that created either of those Plugins to see if it’s something they may already know of and have a solution for?
I would also try seeing if they work with the Genesis Framework, the Genesis Sample theme, or any other Free Genesis Themes to see if the issue shows up or not. If it does then the issue could be a conflict with the Genesis Framework and the plugin itself rather than the Child theme (Ambition).
The Ambition theme doesn’t have anything inside the code that would prevent 3rd Party plugins from functioning. Sometimes 3rd Party plugins conflict with other 3rd Party plugins based on the way they’re developed. Since this isn’t something I developed or have experience with I highly recommend contacting the Devs so you can get the best solution.
