So the actual link tags look correct to me, but you have that amp="" there in the main version, even though that page is not AMP.
Even though Chrome renders the full page correctly, I suspect the search bot on the other hand is getting confused and thinking your full page is AMP, and then getting confused when it finds content AMP does not allow (because its not an AMP page at all).
Removing that attribute and getting Google to recrawl the main page I think will solve it. It will treat it as a full featured mobile page then crawl the amp version from the link seperately.
amphtmlandcanonicallink wrong, put the<html amp>attribute on the normal page or you just misread the search console info. It will still visit the full page, but shouldn't be thinking the full page is AMP without some error there to confuse it, - Fire Lancer
