I have 1522 packages installed: 421 manually installed packages and 1101
automatically installed.

It appears you have 0 manually installed packages in the Cygwin installation you
are looking at, if you used a Cygwin setup-compatible installer, ran exactly the
commands quoted above, and they gave you consistent answers.

It is possible setup has been changed incompatibly and no longer maintains that
field correctly, but in case not, *NEVER* run setup and tell it to remove
obsolete packages: it will remove all non-Base packages that do not have others
which depend on them!
