Uncheck check_box only not working with rspec / capybara tests

I have a nested form that has 4 checkboxes. Currently, everything is working in browser, but I can't get the capybara tests to uncheck the checkbox and save.

Using Rails 4.2.2 and latest versions of capaybara-webkit and rspec

settings.html.erb

  <%= f.fields_for :preferences do |f| %>
    <div class="email-notifications-holder">
      <div class="email-holder">
        <%= f.label :new_match, "Getting a new match each week" %>
        <%= f.check_box :new_match, class: "checkbox new_match_email" %>
      </div>
      <div class="email-holder">
        <%= f.label :match_reminder, "New matches Thursday reminder", class: "match_reminder_email" %>
        <%= f.check_box :match_reminder, default: true, class: "checkbox"   %>
      </div>
      <div class="email-holder">
        <%= f.label :accepted_match, "A Glassbreakers accepted a match", class: "accepted_match_email" %>
        <%= f.check_box :accepted_match, default: true, class: "checkbox"   %>
      </div>
      <div class="email-holder">
        <%= f.label :new_message, "Received a new message", class: "new_message_email" %>
        <%= f.check_box :new_message, default: true, class: "checkbox"  %>
      </div>
    </div>
  <% end %>

edit_account_spec.rb

  it "allows the user to opt out of new match email", :js do
    user = create(:user)
    preferences = create(:preference, user: user)
    sign_in(user)

    visit edit_user_path(user)
    click_tab(t("edit_user.tabs.settings"))

    find(:css, "#user_preferences_attributes_0_new_match").set(false)

    within "#button-container" do
      page.find('.save.main-save-button-edit').trigger('click')
    end



    visit edit_user_path(user)
    click_tab(t("edit_user.tabs.settings"))

    user.preferences.reload
    new_match_email_checkbox = find(".new_match_email")
    expect(new_match_email_checkbox.checked?).to be_falsey
  end

I've tried clicking it, unchecking it, checking it, trigger clicking it, wrapping it around a within block, reloading the db, etc.

    new_match_email_checkbox = find(".new_match_email")
      within(".email-notifications-holder") do
      page.uncheck('Getting a new match each week')
    end

    new_match_email_checkbox.set(false)
