I hope you are well today and thank you for your question.
If you have not purchased this plugin and using the plugin bundled with the theme then you are not direct customer of that plugin so can not update that plugin until it is updated in the theme.
We will update the plugin bundled with the theme in the next theme version.
My wordpress is still asking me to update the Visual Composer plugin, that came with Gillion Theme. After your answer I installed two new updates for Gillion Theme but I still have this note.
