Reply To: responsive text losing text sizes

Why is it reading a css from ‘http://localhost/wordpress-1/wp-content/uploads/2020/07/xts-theme_settings_default-1594369103.css?ver=4.6.0’ ?? (the link is in my staging environment test. It is the same for the live site too….It reads from the uploads of the live site)

Is it normal to save a css in the uploads folder?
