JSM Show Term Metadata
The JSM Show Term Metadata plugin displays term (ie. categories, tags, and custom taxonomies) meta keys and unserialized values in a metabox at the bottom of the term editing page.
There are no plugin settings – simply install and activate the plugin.
Shows Yoast SEO Term Meta
Yoast SEO stores its term (ie. categories, tags, and custom taxonomies) metadata in the WordPress options table, not the term meta table.
The JSM Show Term Metadata plugin can read and display Yoast SEO's term metadata, but it cannot be deleted (as it does not reside in the WordPress term meta table).
