Hi,

If you're using a plugin for cache, please enable ajax for count posts viewed via Customize > Single Post Options > Enable ajax Post View Count

Also, the count from the theme with google analytics will different a bit. Because google doesn't track post viewed for users with same IP and with all wordpress themes, we just can count the posts view when readers go to single post pages - while google analytics exclude a lot of posts viewed with short time. That's why you see it different.
