I suspect that it is just not updating the screen elements dynamically. If you search for the blog (refreshing the list) do you see the name? If this describes the situation we’ve already fixed it in our development version, which should be making its way to the production servers in the next couple of days.
When I create a new blog, the name appears on the blog page itself - but not on the menu (if that is what it is called), or list on the left side of the page. Hitting “refresh” doesn’t seem to do anything. On the left side list it is still shown as “untitled”
