Tarballs are stored under the name from the tarball filename, and purl keeps hex names as they are, so package rules use the default mapping with the name as published.
The filename parser splits versions like 4.1.5-1 at the wrong hyphen and files them under a package like amqp_client-4.1.5, so package rules don't reach them; the docs row says so until the parser is fixed.
