I have been using the AnKing-MCAT deck for a while, and I tried to merge using AnkiHub with the updated deck. Instead of merging, however, it created a duplicate deck (screenshot included).
How can I successfully merge these? The AnkiHub deck is showing that I have already learned cards, so it cannot only be new cards. However, I donβt know if I can delete the old deck and only work from the AnkiHub deck, or if it is not only duplicates in the new deck.
