Subdeck Failure- New shared deck download- Lightyear

Hey all! So I recently downloaded the new Lightyear deck link here:

(https://www.reddit.com/r/medicalschoolanki/comments/nsbfow/the_new_lightyearinfinity_deck_for_step_2/ )

and I am able to import the deck, however I am unable to see the subdecks within the deck itself. I have uninstalled anki, reinstalled the newest version, attempted to go back to an older version, added the hierarchical tag add-on, and deleted the downloaded deck and re-downloaded it all to no avail thus far. I’ve also made sure Windows is fully updated on my computer and I have restarted the computer x2. First to admit that I’m not tech savvy but if anyone could help me out it would be very much appreciated!!
