I checked the files directly, both the pages.sql.gz and the categorylinks.sql.gz files for 20170920.  The page is listed:

$ zcat enwiki-20170920-page.sql.gz | sed -e 's/),/),\n/g;' | grep Computational_creativity | more

Is it possible that your download of the pages.sql file is corrupted?  Do the md5 sums check out?  Or perhaps it is an issue with the tools.
