Hi there,
Please consider that all of the extensions that you see in X > Overview menu item are bundled plugins. You should understand that the concept of a bundled plugin is that we have a contract with the theme developers with the plugin developer to include the plugin files in our theme. You can use that plugin within the theme with no [problem and you do not need to activate any of those plugins using their purchase keys as you do not have any purchase key, the messages are all the default ones of the plugin and you should not worry and your usage of the plugin is completely legal.
Please consider that the bundled version of the plugin which you have as you installed the theme will be updated by us. We will release the plugin updates periodically but it will not be necessarily in sync with the plugin updates, and we may be a little be behind the versions, the reason is that on each release we check the compatibility of the plugin with our theme.
For more information please read the Bundled Version Section of the plugin below:
Thank you.
