"'en-US' – no return tags" Hreflang Tags Error on comment pages

I am all very new to this and just started learning about Hreflang tags while implementing a translations of my recipe site using Bogo plugin (functionality of which matches what I need perfectly).

So being very new to it I need some help figuring out how the issue with “‘en-US’ – no return tags” Hreflang Tags Errors I am seeing reported in google webmaster tools can be fixed.

Errors read “URLs for your site and alternate URLs in ‘en-US’ that do not have return tags.”

All errors seem to be related to WordPress comment pages (I have comments pagination enabled to prevent pages with many comments from being too long). But can also be that google didn’t parse all the new page translations yet.

Here is one page reported to have the issue:
http://www.enjoyyourcooking.com/main-dish-recipes/boiled-snow-crab-legs-oldbay-seasoning.html/comment-page-3#comments

The Canonical tag appearing in this page (Page A) is:
<link rel=”canonical” href=”http://www.enjoyyourcooking.com/main-dish-recipes/boiled-snow-crab-legs-oldbay-seasoning.html/comment-page-3#comments&#8221; />
(So the page 3 of comments for the original article available on http://www.enjoyyourcooking.com/main-dish-recipes/boiled-snow-crab-legs-oldbay-seasoning.html)

And the 2 Hreflang alternatives are:
<link rel=”alternate” hreflang=”ru-RU” href=”http://www.enjoyyourcooking.com/ru/main-dish-recipes/boiled-snow-crab-legs-oldbay-seasoning.html&#8221; />
<link rel=”alternate” hreflang=”en-US” href=”http://www.enjoyyourcooking.com/main-dish-recipes/boiled-snow-crab-legs-oldbay-seasoning.html&#8221; />

The translation for that recipe is supposed to be the following page (Page B), but of course it will not have all the same comments:
http://www.enjoyyourcooking.com/ru/main-dish-recipes/boiled-snow-crab-legs-oldbay-seasoning.html

The Canonical tag appearing on Page B is:
<link rel=”canonical” href=”http://www.enjoyyourcooking.com/ru/main-dish-recipes/boiled-snow-crab-legs-oldbay-seasoning.html&#8221; />

And the 2 Hreflang alternatives on this one are:
<link rel=”alternate” hreflang=”en-US” href=”http://www.enjoyyourcooking.com/main-dish-recipes/boiled-snow-crab-legs-oldbay-seasoning.html&#8221; />
<link rel=”alternate” hreflang=”ru-RU” href=”http://www.enjoyyourcooking.com/ru/main-dish-recipes/boiled-snow-crab-legs-oldbay-seasoning.html&#8221; />

Am I correct to assume that the error reported by google relates to the fact that the RU page doesn’t link back to the EN page with “comment-page-3#comments” in the URLs but to the main page URL instead? Or am I wrong here?

What is the proper way to organize hreflang tags in the situation when comments are paginated but don’t match in both languages?

Thank you for any help in advance.
