Thank you for pointing to right directions. In fact this goes far deeper than we thought. We did the plugin conflict check with site health but it did not give any errors for plugins. So we dig deeper and asked from WPRM support as well.
As you said there is two instances writing Schema data.
view-source:https://flavorado.com/en/cabbage-rolls/
First one is WPRM because it writes ingredients as well.
<script type="application/ld+json">{"@context":"http:\/\/schema.org\/","@type":"Recipe","name":"Cabbage Rolls","
The other one is Yoast
<script type="application/ld+json" class="yoast-schema-graph">{"@context":"https://schema.org","@graph":[{"@type":"Article","@id":"https://flavorado.com/en/cabbage-rolls/#article","isPartOf":{"@id":"https://flavorado.com/en/cabbage-rolls/"},"author":{"name":"Flavorado","@id":"https://flavorado.com/en/#/schema/person
Google schema validator sees them also as two different instances on Detected items. The later (Yoast) has some minor errors and author type is “person” for some reason. Also article type is “article” not “recipe” as in first one.
But I am really puzzled where to change those things as there is no settings for them? And how we can have just one schema set up?
Thank you.
