How do I stop my blog page from displaying same content as home page?

I am trying to have a separate page to display my posts and ensure the home page remains as the front page.

I have gone to settings > reading and set the front page as home and the posts page as blog. But when I visit url/blog, it displays same contents as the home page rather than my blog posts.

My .htaccess file looks like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Could this be a problem?
