What is in the Current Webpage Preview pane is not what appears on the web.

[Emmo]

I have tried to create a new webpage but when I export it is does not mirror what is shown on the web. I have even saved this page http://www.emmerson.talktalk.net/2016%20Blog.htm as http://www.emmerson.talktalk.net/2017%20Blog.htm but with the same result. What am I doing wrong?

I have noted that the files of 2016 are the same size as 2017. Running on Vista/Designer Pro 11
