Issue with quote in SEO Title

Hello,

It works for a page, a post, a product, but NOT for a product category.

I’d just tried for these 4 types of publications and for a product category, Rank Math does not see that the keyword “boucles d’oreilles” is IN the title of the publication:
In General / Basic SEO, there is this error:
Le mot clé principal n’apparaît pas dans le titre SEO

In another term: “The main keyword does not appear in the SEO title”

My tests:

In the title of product-cat, if I add a space after “boucles d’oreilles” (as this “boucles d’oreilles “), the keyword is immediately detected.
If I remove this space, at the end, the keyword remains detected. So, I wait few seconds, and I save the product category.

And as soon as it is saved (so without the space: “boucles d’oreilles” for the title), the keyword — boucles d’oreilles — is no more detected and SEO score is … low.
Another time: FOR the product categories only.
Strange.

Thanks a lot if you have any tips for this issue.

Best regards
