Hi George,
Yes, this is the default before if there are no posts in an archive page – it uses the no-results.php template.
For one, if you’re using the Child theme, you can make a copy of no-results.php, then make a conditional statement to implement “get_the_archive_title()” when necessary.

You can also use a Hook Element and add a code like this for instance:
<?php
echo '<h1>'. get_the_archive_title() . '</h1>';
?>
