Category filter problem

Hello, I have an issue with a filter on a category.
I created the various feeds for different categories a few years ago, and they’ve always worked.
For the past few weeks, one of the feeds with a filter on a specific category no longer finds any products.

It’s possible that a colleague renamed the category but didn’t change the slug.
I tried creating a new feed, filtering, for example, the products with a price under €200. This way, I can see the products priced between €0 and €200, but those belonging to that specific category do not appear.

What could this depend on?
Thanks.
