Problem with links

Hi!

Website https://www.unive.com.ru

My permalinks settings: I chose Custom Structure and added: /category/%category%/%postname%/

I use plugin Landing pages by PluginOps for this page https://www.unive.com.ru/category/software/gracian-the-oracle. I wrote them. A s a result I got two categories in the link https://www.unive.com.ru/category/category/software/

Breadcrumbs – Yoast SEO plugin. But I think it doesn’t influence on links.

When I go to the landing page, the link is like this https://www.unive.com.ru/category/software/gracian-the-oracle/ – it’s OK.

But when I click on software category, the link is like this https://www.unive.com.ru/category/category/software/

How can I delete the extra category in the link https://www.unive.com.ru/category/category/software/, so that I can get this link https://www.unive.com.ru/category/software/ ?
