Can’t make new Shortcodes

Hey hey,

I have a few issues while using your plugin. First of all I add a new recipe. I copy the id-no (because there isn’t any addingbutton at the classic editor) and insert it into a new blogpost with your shortcode. But it doesn’t work anymore. The recipe is publicated also the blogpost. But at the position where the recipe should be showing there is a vertically rose line.
Please help
