no, it should not be a problem because Bundled plugins do not have their own licenses. This means they cannot be activated mean registered for updates. So you can safely ignore any plugin activation/registration messages.
About Pictures, menus, footer widgets:
If you can’t see them properly then you have to assign them from your side. You can see documentation help for this. As like for menu you have to go Appearance => Menus, for footer and sidebar widgets you have to go Appearance => Widgets and have to set.
About preview images most of the theme (95%+) don’t include preview images with purchased download instead used placeholder. So, you have to edit those post/pages/slider to set your own images. You can see documentation help for this.
