Did a full rebuild the front facing site only seems to go back to 2013 but the posts do go back to 2007, can’t fathom why it’s not showing them all yet but there are at least on the server. I did note that when I went in and pressed updated from an older post a few more appeared at the end of the archive page 
but not up to that date and not sure it was the next few or just some random older ones or such just a handful more appeared at the end of archive page - very weird
