One of our articles is available in different language variants - English, French and German. Most of the Hreflang tags seem fine.

The English article can be found under two URLs:

-https://www.example/hr/recruitment-and-onboarding/delicately-handling-dismissal-what-not-to-say (DEFAULT URL - and is en-US) - (Page A) -https://www.example/en-us/hr/recruitment-and-onboarding/delicately-handling-dismissal-what-not-to-say - (non-canonical and isn't indexed) - (Page B) 

^^ the content is identical and in the source code for the en-US page, the canonical link points to Page A (see URLs above) - I assume this is correct.

But in terms of Hreflang, Ahrefs said the target page (refer to Page B) is missing a self-hreflang tag and isn't being linked to from the de-DE, fr-FR, en-US pages.

​

Should the non-canonical page include a self-reference tag (pointing to Page B) AND should the other pages link to Page B?

At the moment, the non-canonical page references Page A in the code for the en-US tag (and the x-default tag). And it references the fr-FR and de-DE URLs.Have we done something wrong?
