Issue details

Similar or duplicate pages of a website must specify the canonical page to instruct search engines to show the most authoritative (canonical) version of the page in search results.

A redirecting URL specified as canonical can be misinterpreted by the search engines; such conflicting instruction can be ignored. As a result, wrong (non-canonical) page version can be indexed.

How to fix

Review the list of pages with canonical links pointing to a redirecting URL.

Replace the redirecting canonical links with the direct links to the valid 200 (OK) page versions that you want to be indexed in search results.

Chris - Both of the files you attached are same.

Also to confirm. For eg.

Both of the below 404 URL's
https://deals.skinneymedspa.com/product/coolsculpting-mini-double-chin/
https://www.skinneymedspa.com/deals/product/coolsculpting-mini-double-chin/

I couldn't find this product in skinney's shopify website. So should I redirect them to skinney Coolsculpting double mini chin service page here . 
https://www.skinneymedspa.com/coolmini-double-chin-reduction/

Let me know. Thanks.

Yes redirect there please 

DONE
