Filters don't work anymore for new product

[havana1982]

In my shop, I've been using Search & Discovery to set up filters. It has always worked flawlessly.

For some reason, it doesn't work anymore when I add a new product. It does work in English, but does not work in other languages. Translations are set correctly (I think).

Example. This product has filter: country = Italy.

When you visit the shop and turn language to English, the product is shown when you filter on Italy as it should.

However, when you switch to another language, the filter doesn't work anymore. That's strange, because the meta field is actually translated (see screenshot).

What am I doing wrong?

BTW: The problem only occurs on new product. When I re-activate old product, it works fine.
