So no version or repo information for eight installed packaged.
This is a bug.
This is in a fully updated Fedora 27 installation as of 2017-11-14.
This has something to do with how DNF formats output.
It sometimes splits output to multiple lines, especially when using grep.
We'll fix the problem.
The issue is solved by dnf-3.0.1-1 that was released into rawhide.
