Adwords remarketing tag applied by Tag Manager, not showing in Adwords Audiences.

[#1]

I have Tag manager applied and a re-marketing Tag added to the site.  However when I go into Adwords audiences it states that "We haven't detected the Google Analytics re-marketing functionality on your website"  Even though if I use the Tag Assistant it goes green so I believe is added correctly.  Here's a good page to test it on:  https://www.bestwaystore.co.uk/10-x33-x6-hf-ocean-tech-sup.html

Any hints would be gratefully received.  Please note the Tag was applied 23rd March 2018.

Regards

Rob.

Yes - this is annoying and misleading... the system doesn't seem able to identify the tag if implemented through GTM - you should be fine - it's just a false negative.
