How to set Home page title in WordPress
If you use the WP plugin All in One SEO Pack, and then go into the plugin’s general settings, that should work. We had the same issue and wrote a pretty detailed blog post about it: Change Title of a WordPress Home Page.
Have you tried looking at admin > appearance > editor? then checking header for the title tag and seeing if you or someone else change the title to the old blog name? If not then I’d suggest doing so and changing it to
<title><?php wp_title(' '); ?></title>
