Form_for action has .id added to URL during edit action - Rails 3

I have a form where, when I submit during the editing action, the .id is added to the postulate when it shouldn't. The form works correctly during creation, but is not updated.

Here's the action of the url while editing.

http: // localhost: 3000 / members / 1 / profile.1

Here is my form

<%= form_for([@member, @profile]) do |f| %>
<%= f.label :first_name %><br />
<%= f.text_field :first_name, {:class => "txt-field-short"} %><br /><br />
<%= f.label :last_name %><br />
<%= f.text_field :last_name, {:class => "txt-field-short"} %><br /><br />
<p><%= submit_tag "Create Profile" %></p>
<% end %>

This is my route for this association.

resources :members do
  resource :profile
  resources :orders
end

Here are my steps for creating, editing and updating in the profile controller

def create
 @member = current_member
 @profile = @member.build_profile(params[:profile])

 respond_to do |format|
  if @profile.save
    format.html { redirect_to(member_profile_path, :notice => 'Profile was successfully     created.') }
  else
    format.html { render :action => "new" }
  end
end
end

def edit
 @member = current_member
 @profile = @member.profile
end

def update
 @member = current_member
 @profile = @member.profile
 respond_to do |format|
   if @profile.update_attributes(params[:profile])
     format.html { redirect_to(member_profile_path(@profile), :notice => 'Your profile was successfully updated.') }
  else
    format.html { render :action => "edit" }
   end
 end
end

What adds profile.id to the post action?
