I created an archive of tags for blogs. And right now it says, "Posts Tagged 'Air to Water.' I would like the title it's just Air to Water without the apostrophes as well.
The heading "Posts tagged..." comes from your theme, Toolset doesn't affect that part of the page (it replaces the content area of the page, and that heading comes before the content).
To change it you should locate the source and modify it (within a child theme).
With the default twentytwentyone theme, for example, the equivalent heading is generated within the archive.php file, using the core WordPress function the_archive_title().
