Enhanced Ecommerce Google Analytics Plugin for WooCommerce

I activated the plugin but seems it doesn’t work correctly.
Here is my page https://graff.io/?product=japanese-floral-pack-by-hamano-masato
in source code there is

(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

  ga('create', 'UA-42175789-1', 'auto');
  ga('send', 'pageview');

But at this page
https://carewaywellness.com/shop/foot-care/hermell-imitation-sheepskin-heel-protector there is such code

(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
	(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
	m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
	})(window,document,'script','//www.google-analytics.com/analytics.js','ga');
	ga('create', 'UA-41848238-1', 'auto');
	ga('require', 'displayfeatures');

	ga('send', 'pageview');
	ga('require','ec','ec.js');

at my page ga(‘require’,’ec’,’ec.js’) is missed
Add Universal Analytics Tracking Code (Optional) box is checked
Please can you help me what is wrong?
