Breaking links FAQ

Hi there,

I just did an adjustment in one of the FAQ categories on my website. Now the FAQ which belong under this category are gone.. I think it has to do with the fact I changed the slug. Now the new slug is: https://vakantieadresonbekend.nl/ufaq-category/faq-prijzen-en-extras/ and it was the same only without [-category] but I’m not sure how to change this so the FAQ are shown again under this category (just like with the other categories (see this page as an example: https://vakantieadresonbekend.nl/veelgestelde-vragen/)? Can you help please?

Thanks! Best regards Marjon
