Why Sub Category Links aren’t working

Created some new subcategories but when I set up the links, I get a 404 error even if its working on backend. e.g. this link doesn’t work

https://www.jadeed.store/categories/personal-care/electric-massager.html

But the version I had to implement based on a filter? That worked but it was a makeshift solution

https://www.jadeed.store/categories/personal-care.html?cat=267_electric-massager

Problem is that its not a one time thing and several categories and their subcategories are having the same issue. Whats the issue?
