    Hello Steven Lancaster,

    Is this the default BlogPosts control and its BlogPosts designer? Does the problem persists if you remove the control from the page and add it again? Can you provide steps to reproduce the problem locally, because this is not the default behavior of the control. You have changes something to the designer or some properties have been set inappropriately.
