wordpress Comments error

I am having a problem in my WordPress site, when I create a new post or update a post to my site automatically get 2-6 comment by my post(Author is post title and comment is post content).i have to delete manually those comments. i am getting this error almost 10 days.i thought it might be theme or plugin but i check all of them by disabling. but the same thing happens if i disabled all plugin and use another theme.

I am using the latest version of WordPress and my host is siteground.i couldn’t find any solution and why this is happing.
