Woocommerce filter urls showing in crawl results, but not indexed?

[JustinMurray]

I'm getting 100's of Duplicate Content warnings for a Woocommerce store I have. The urls are 
 etc

These don't seem to be indexed in google, and the canonical is for the shop base url. These seem to be simply urls generated by Woocommerce filters.

Is this simply a false alarm from Moz crawl?

Hi Justin:

I have a client with this problem. All of the filter URLs are crawled by Moz, show as duplicate content in Moz, have 302 warnings in Moz. All of them canonical back to their respective category pages. None appear on WMT/Search Console, but doing a similar "site:URL" search on Google shows they are indexed. I'm curious what you've done in the last year to resolve this? Or have you only tried to resolve via Sitemap submission, and did that work for you? Thank you!

Just an fyi for anyone who is using the Woocommerce and Yoast plugin, you can remove the additional features, custom attributes, and other Taxonomies that you may not want indexed via XML Sitemaps - Taxonomies.

I see now, thank you good sir! The answer to that question is likely "no" Now to hunt for a solution in the WordPress/Woocommerce/Yoast environment.

Hmmm thank you for the feedback. Google is not indexing these though...

If I google a phrase "egardwatches.com  filter 128" to find this url  -http://www.egardwatches.com/shop/?filter_additional-features=128 -

It does not appear in Google results, and it has the ? query indicator, which should tell Google it is dynamic?

Are you sure this isn't an issue with Moz crawl only?

How can it be duplicate content if it isn't even indexed?
