While checking T206585, I checked Special:Deletion tag log, I found two articles that were mark for deletion with `afd tag ` but were not in the NPP feed ( the pages are not found in `pagetriage_page`).
(1) [[ https://en.wikipedia.org/wiki/Nurgul_Jones | Nurgul Jones ]] article has the following record in Special:Deletion tag log
{F26528293}
The article has the proper template {{Article for deletion/dated|page=Nurgul Jones|timestamp=20181008215632|year=2018|month=October|day=8|substed=yes}} and Category:Articles for deletion
The article history shows that the article was nominated for deletion.
{F26528560}
Note: from the screenshot above, the second line form the log [[ https://en.wikipedia.org/wiki/Atlas_(musician) | Atlas (musician) ]] article is present in the feed.
(2) The same for [[ https://en.wikipedia.org/wiki/Evolution_Tour_(Anastacia) | Evolution Tour (Anastacia)]] article -
