Last week we changed our URLs to be only HTTPS (they were a mixture of both for a couple of weeks). We did this by adding a 301 redirect from HTTP to HTTPS.
However, the On Page Optimization is now showing the same URL/Keyword twice for a few of our pages. One has a grade A, one has a grade B. The grade B complains about "Rel Canonical" not matching, but the other doesn't.
This is pretty confusing - should it not have crawled the pages and noticed the 301 redirects and combined the entries or removed the HTTP ones?
