FAQ Schema and WPML translation

1. First I fill in the questions and answers in the English version of the page and then turn on “Enable Schema Support” in the settings:

So the code is:

<!-- wp:uagb/faq {"block_id":"84b9b4a0-ed17-4334-9088-cd3212d22bea","enableSchemaSupport":true,"schema":"{\u0022@context\u0022:\u0022https://schema.org\u0022,\u0022@type\u0022:\u0022FAQPage\u0022,\u0022mainEntity\u0022:[{\u0022@type\u0022:\u0022Question\u0022,\u0022name\u0022:\u0022First question?\u0022,\u0022acceptedAnswer\u0022:{\u0022@type\u0022:\u0022Answer\u0022,\u0022text\u0022:\u0022First answer.\u0022}},{\u0022@type\u0022:\u0022Question\u0022,\u0022name\u0022:\u0022Second question?\u0022,\u0022acceptedAnswer\u0022:{\u0022@type\u0022:\u0022Answer\u0022,\u0022text\u0022:\u0022Second answer.\u0022}}]}"} -->

<!-- /wp:uagb/faq -->

2. Then I create a new page in WPML with translation into Polish (for example) using its Classic editor:
https://image.prntscr.com/image/uIlTot1VRQ_ja7lFkh1THA.jpg

3. Now I have 3 textareas to translate (uagb/faq, uagb/faq-child and another uagb/faq-child). I only change the text of the questions there.

And here is the output on the translated page:

So you can see that for the visible part of the page this is completely translated, however, the Scheme for Google’s search results remains in English.

Perhaps this is due to block_id conflict? Anyway, is there any way to fix this?
