Tag Title of course category pages cannot be changed

Hi,

I’m having an issue with my course category pages. The <title> tag of the pages seems to be fixed based on a pattern that I can’t change. All the pages related to, for example, “All Courses,” categories, and sub-categories of courses have the same <title> tag, “Todos os Cursos – A Arquiteta”. Even if I change it internally or use any SEO plugin like Yoast or RankMath, these pages don’t follow the defined rules. This issue affects the SEO of my pages, as they end up with a duplicated <title> tag on various course category pages.

Example link pages
https://www.aarquiteta.com.br/todos (All Courses page)
https://www.aarquiteta.com.br/cursos/ (Category Page)
https://www.aarquiteta.com.br/cursos/archicad/ (Sub-Category Page)
https://www.aarquiteta.com.br/cursos/autocad/ (Sub-Category Page)
