Inconsistent .pgn database files

Champions Showdown: Chess 9LX 2022 (Sep 12, 2022 - Sep 16, 2022)

I noted this before and am wondering if it will be addressed and corrected. (see Forum "Site Feedback" "Topic: Fischer Random Chess Championship 2022 qualifying rounds database.pgn" (15 days ago)

I have downloaded the complete event .pgn-database for both of these contests. Neither will work properly with ChessX on my Linux computer. These files show only very few first moves & the result, and not the complete games.

I have also downloaded several individual game .pgn's from these same events. Those files work properly with my ChessX.

It appears upon viewing the individual game .pgn files along side event database .pgn files with a text editor, that the necessary .pgn criteria is not identical in each file concerning same games.

The "Variant" line, and the "SetUp" line are included in the individual game .pgn files but missing in the event database .pgn files, and the "FEN" line (case sensitive) is misspelled in the database .pgn files.

It "would be" much more convenient to download the entire event database .pgn file as opposed to downloading each individual game .pgn file. And I believe that is the intent of Chess.com.
