Need Help Accessing Downloaded Decks

I have Anki downloaded to my desktop, and I have it synced to my AnkiHub. I am trying to import the ANKing MCAT deck. I have the file downloaded on my computer, and when I go into Anki to import the file, it says the import is successful and the cards are already in my account. It allows me to “preview” them, but in my desktop, only about 100 of the many thousand cards are present. I had a similar issue attempting to import a Milesdown deck as well.

They are all there in browser view.
