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.
Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.
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.
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.
Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).
