Duplicate title on category pages

I want to make different page title and descriptions for category pages.

Example of duplicates title and descriptions:
https://www.secretfoodtours.com/recommendations/blog/category:london
https://www.secretfoodtours.com/recommendations/blog/category:london/page:2

I’m new with Grav and I want to learn more. Can you help me fix this?

I have FTP access, so I can edit manually the pages.

Thank you!
