If you have default settings, slider is always responsive. And because we don't know what you set exactly, it's difficult to say what you did in the back-end. Please check the following screenshots of how responsive supposed to look like:
You can disable slider on mobile under Slider Revolution > Slider Settings > Layout & Visual > Mobile section. However, as far as we know, slider does not have an option to replace one slider with another on mobile only.
We need an access to your WP dashboard to check what you did wrong. So if you want to send us such access, please use contact form on the right at https://themeforest.net/user/muffingroup#contact
