Weird and Random Urls being generated

I recently moved my website from a static site crownedstudio.com to wordpress platfrom crownedstudiosalon.com

i set up the htaccess file for redirect from the old to new. all of this is fine.

i use google webmaster tools and now i am seeing random url being generated

for example this URL
https://www.crownedstudiosalon.com/blog/?cat=1&paged=2
https://www.crownedstudiosalon.com/blog/category/pasadena-salon-news/page/2/ (pasadena salon news isn’t even a category and it never was)

this url leads to a 404 and was generated from my new site, i have never used this url config before and i have not idea how this are happening
