Ruby on Rails App Displaying Unwanted Data [duplicate]

This question already has answers here: What is the difference between <%, <%=, <%# and -%> in ERB in Rails? (7 answers) Closed 3 years ago.

Whenever the following code runs i get extra output on the page which looks like the garbage on the bottom. I have tried to see if it is in my migrations or function calls, but they all seem to be pretty clean (not much too f.name). If needed I can provide a copy of my migrations and schema.

<%= @subject.Name %>
<%= @subject.formulas.each do |f| %>
  <div class="entry">
    <h3><%= f.name %></h3>  
  </div>
<% end %>

The extra output is:

Change

<%= @subject.formulas.each do |f| %>

to

<% @subject.formulas.each do |f| %>
