I’m not sure I understand you.
The quoted section indicates that manjaro-pacnew-checker was being run after updates.
It would look like this:
But you dont have any of the ‘fruits’ of properly handling those files.
Normally that means the user has ignored them for however long.

The only conclusion I can draw from that is that you had them, did not use them, but removed them.
(that or there is a severe bug in manjaro-pacnew-checker that has only so far noticeably affected you)
