No Icons Visible on Foodica Lite

I’m still using the classic editor and I’m trying to use the Recipe Card plugin on a site with Foodica Lite. In your theme documentation you wrote:

“If you’re using the Classic Editor, you can find the recipe shortcodes in the Visual editor mode. There should be 2 icons to add Ingredients and Directions in your posts”

However, I cannot see these icons or shortcodes in the visual editor mode. Does this mean that there is a plugin that could be causing a conflict and that’s why the icons are not visible?

Thanks!
