Shortcode stops appearing

So i bought the theme. Initially it was good and i added many items. All of sudden, the editing page does not show your shortcode, only text.

The default theme is travelwp-child. So if you like to look at it, please switch to restaurantwp-child.

Your urgent help is appreciated.
