Rails: Devise with 2 models, logout logs out both

I am trying to implement a second devise resource of users to my Rails app. Log in works, but currently when logging out in one section, logs out both.

How can I set up my application in order to be able to keep both separated?

routes.rb:

devise_for :users, :path => 'users'
devise_for :admins, :path => 'admins'

application_controller.rb:

private

# Overwriting the sign_out redirect path method
def after_sign_out_path_for(resource_or_scope)
  if resource_or_scope == :user
    collection_path
  elsif resource_or_scope == :admin
    new_admin_session_path
  else
    root_path
  end
end

# Overwriting the sign_in redirect path method
def after_sign_in_path_for(resource)
stored_location_for(resource) ||
  if resource.is_a?(User)
    collection_opac_path
  elsif resource.is_a?(Admin)
    admin_root_path
  else
    super
  end
end

1.html

<%= link_to 'Log out', destroy_admin_session_path, :method => :delete %>

2.html

<%= link_to 'Log out', destroy_user_session_path, :method => :delete %>

LOG upon logging out user:
