This isn't a bug, it's however concerning that you haven't read the output of
pacman for 7 years and left .pacnew files unresolved.

As you can see, the files has been missing from the backup array thus pacman was
not aware of it. It does what it's suppose to do and preserves it's old file and
stores the new files as `.pacnew`.
This is documented in the manpage:
