Remove ” Browse Category : ” from Archive title

If you are using child theme. Add filter in the functions.php of child theme like this.

add_filter('get_the_archive_title','wpse_224884_filter_archive_title',10,1);
function wpse_224884_filter_archive_title($title){
   if ( is_category() ) {
      $title = sprintf( __( '%s', 'shaped-blog' ), single_cat_title( '', false ) );
   } 
   return $title;
}

Or

Copy the entire function into functions.php

function shaped_blog_archive_title( $before="", $after="" ) {
    if ( is_category() ) {
    $title = sprintf( __( '%s', 'shaped-blog' ), single_cat_title( '', false ) );
  }else if ....//remaining code
}

without if ( ! function_exists( 'shaped_blog_archive_title' ) ) :

The only change you need to do is remove Browse Category: in line 4
