</span>
                <meta itemprop="priceCurrency" content="RUB" />

Answer 1

this is micro-markup, he does not see it normally. Extended snippets with such errors cannot be seen

Answer 2

Commodity micromarking is not filled in the proper volume.
What will it affect? - Nothing. Markup is not a ranking factor, and can be used to some extent to form a snippet in SERP. Or maybe not used.
In practice, I have never encountered the fact that the elimination of such problems somehow affects the positions, especially when it comes to individual commodity cards. If there are resources, it can be eliminated.
