Google Analytics tag not detected

Hi,

I would like to integrate google analytics to my website through WooCommerce Google Analytics, I follow the instruction provided by google but my tag is not being detected when I test the link.

In the instruction I am directed to confirm that I have checked the box “Use Global Site Tag” which should be located just under the tag code entry but I cannot find it anywhere on the settings page.

Am I doing something wrong??

The page I need help with: [log in to see the link]
