Why doesn't Google see crumbs on a multilingual site?

Question

Google

There is a site site.ru
the site has an English version with the category /en
Russian - site.ru/blog/2
English - site.ru/en/blog/2
there are such tags on each page

<link rel="canonical" href="/blog/1">
<link rel="alternate" hreflang="ru" href="/blog/1">
<link rel="alternate" hreflang="en" href="/en/blog/1">

there is a breadcrumb markup on both versions, here is a simplified version of the English. versions

<div id="breadcrumbs">
   <ul>
    <li itemscope="" itemtype="http://data-vocabulary.org/Breadcrumb">
      <a href="/en" itemprop="url">
        <span itemprop="title">Home</span>
      </a>
    </li>
    <li itemscope="" itemtype="http://data-vocabulary.org/Breadcrumb">
      <a href="/en/blog" itemprop="url">
        <span itemprop="title">Blog</span>
      </a>
    </li>
    <!--Последний елемент с заголовком статьи -->

The Google microdata validator did not reveal any errors in either the English or Russian versions.
Russian breadcrumb is displayed great. But on the English-language pages of the site, for some reason, a Russian baby is displayed. I checked how English-language pages look like in Google through a proxy, and it really showed me English. site version. But the baby is Russian.
Also in the Search Console, I see that micromarking was found only on Russian pages. And only one page with the /en prefix. Even in the first two weeks.
Added microdata in early August. It's been like 2 months now.
What could be the problem?
