Unfortunately, there is nothing to be done and the plugin developer choose to leave this option there to encourage people to purchase the plugin. The purchased version will include
1 - You will be able to download slider templates from inside the plugin, while on the version that comes bundled with X you will need to download from this link: https://revolution.themepunch.com/free-slider-exchange/ and then import to the slider.
2- The purchased version offers direct ThemePunch support, while on the bundled version we will provide you support.
3- The purchased version will give you access to premium non-standard slider templates.
Besides that, regarding the slider functionalities, the plugin that comes bundled with X offers 100% the same functionality as the purchased version.
Hope it clarifies.
