Universal Movie Scraper not fetching certification from IMDB

I noticed all my recently scraped movies were rated NR. I Checked the logs and found that

The tt0944835-reference.html file was created and contains all the information. I re-scraped movies that did have a certification rating on them and watched them lose it.

I'm on metadata.universal 4.1.8 and metadata.common.imdb.com 3.0.3, with Kodi 17.6 Git:20171114-a9a7a20.
<setting id="imdbcertcountry" value="United States" />

All other URLs from IMDB work just fine:

While debugging, I found that if I changed the 2 to a 5, on lines 5 and 6 below, 350 and 351 in metadata.common.imdb.com/imdb.xml, everything worked just fine, but can't figure out why 2 or any other number throws the error.
