Breaking Slider

Anyone know what would be causing the slider to break on mobile & tablet size screens? Have done the plug-in on/off diagnosis, down sized slides, turned off/on responsiveness and mirrored all on a test server. Test server turned off responsiveness and tested it with Jetpack. No difference. Otherwise, love this theme!
