Most probably CPANTS databases are being regenerated from scratch due to major changes in Kwalitee metrics or updates of relevant modules/perl. Usually this maintenance takes about a day or two, and some of the information may be old or missing tentatively. Sorry for the inconvenience.
If you use Mac OS X >= 10.6, use gnu tar (/usr/bin/gnutar) to avoid PAX headers. It's also important to rename (shorten) long file names (>= 100 characters) in the distribution.

Add a README to the distribution. It should contain a quick description of your module and how to install it.
Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.
Add a section called "LICENSE" to the documentation, or add a file named LICENSE to the distribution.
Add =head1 LICENSE and the text of the license to the main module in your code.
Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.
Error:
Provide a short description in the NAME section of the pod (after the module name followed by a hyphen) at least for the main module of this distribution.
Make sure that the main module name and version are the same of the distribution.
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.
Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
List all modules used in the Makefile.PL/Build.PL in META.yml configure_requires
