Rel Canonical and Moz Crawl

[S.S.N]

we have  Rel Canonical tags set up on a few pages. When viewing the page source, the tags are correct. However, Moz Crawl results show the opposite.

for example the page source, correctly shows, URL  X with a Rel canonical Tag of URL Y
but..  Moz crawl is showing URL Y with a Rel Canonical Tag of URL X ..any thoughts why this would happen? which should i trust more?

Assuming you are absolutely sure your page has been set up correctly, you should trust that data source more. How is Google showing up the pages when you're performing a 'site:www.yoursitename.com' search?

Lets not be hypothetical. If the exact url is shared, may be you will get a concrete and exact reply !!

[S.S.N]

we're actually 301 redirecting the page as well. should we remove the rel canonical?

It's a product id url (open cart default) vs a keyword optimized url

We don't want the product id url showing up on search results, as the content of the page doesn't mirror the Keyword optimized url -   (Shopping cart is missing, image is missing. basically it's just text)

[S.S.N]

looks like after today's crawl, moz is correct.  (the tags were wrong on site, and we fixed it.. but it didn't show up correct in the test crawls we did earlier this week).

Sara, if you're 301ing a page that also includes a rel=canonical directive, the rel=canonical will not be seen because the server redirects the user before they get to the page. If the pages are identical, you can rel=canonical one to the other and both URL will be available to the user.  A 301 will prevent a user from landing on that page.
