Focus Keywords doesn’t change

Greetings,

I need help please, the plugin doesn't save the focus keywords and acts suspiciously.

I deactivated all plugins and didn't fix the issue.

the issue popped out on 12/7, so I think that the new version is the cause.

the error mentioned in the screenshot appears when I make changes to focus keywords and update the product.

1 - if I duplicate a product and change the focus keywords, it doesn't change/save.

2 - if I duplicate a variable product and change the focus keywords without changing the title or description, it does change/save.

3 - the SEO score shown on the " Edit Product " page is low due to the difference in focus keywords and title/description " for example ( 8 / 100 ) ", but on the " All Products " page all recent products have the same score ( 79 / 100 ).

4 - if I use the second method mentioned above and edit the title & description it will change and the SEO score on the " Edit Product " page will be higher " for example ( 87 / 100 ) " but on the " All Products " page all those products have the same score ( 24 / 100 ).

WordPress 6.4.2 running Woostify theme.

Rank Math SEO Version:     1.0.208.1
