Hello,
In this case you might have to reach out to the deck’s author, as this particular deck is not maintained directly by Ankihub.
From the looks of it, other users seem to have had a similar issue with this deck ([Wiki] Dura Deck by chriscross) and it does not appear to have been updated in the last year.
Please let me know if that answers your question, and if there’s anything else I can help with.
