Episode's rating is not included in export

I have rated the episode "Ep 174: Robert Smigel & Justin Willman (Magical Comedy)" (https://www.imdb.com/title/tt32157807/) of the series "We Might Be Drunk" (https://www.imdb.com/title/tt21614782/) on 2024-11-24. This rating is shown on the episode's page, the series's episodes list page and my "Your Ratings" page (https://www.imdb.com/user/ur1808649/ratings/). However, it has never been part of any export (https://www.imdb.com/exports/) I have requested since then. Is this a known problem? (I have not tried removing my rating and rating the episode again yet as I do not want to interfere with any debugging.)
