Wikipedia dumps raw database tables in a gzipped SQL format for the English language Wikipedia (enwiki) approximately once a month (e.g. dump from February 1, 2018)...By default, the script grabs the latest dump (available at https://dumps.wikimedia.your.org/enwiki/latest/), but you can also call the database creation script with a download date in the format YYYYMMDD as the first argument.
I'd guess the tool is working off an out of date article.
