Hello! In this code, title and content fields show inline errors properly but staple_food and main_dish doesn't. Is there a mistake?

<%= bootstrap_form_with(model: @recipe_form, url: @recipe_form.persisted? ? recipe_path : recipes_path) do |form| %>

  <%= form.text_field :title %>
  <%= form.text_area :content %>

  <%= form.fields_for :genres do |g| %>
    <%= g.text_field :staple_food %>
    <%= g.text_field :main_dish %>
  <% end %>

  <%= form.submit %>
