I was trying to add an add-on and unsure what exactly I did but now all my cards are showing up as one-by-one cards, including from the Anking deck and other decks. Does anyone have an idea how I could change back to their original cloze-type
Please try resetting your local changes. To do this:
Go to browse in your Anki → at the top click on ankihub addon tab → press reset all local changes
This will restore everything to what AnkiHub has unless you have specifically protected those fields
If it still does not work, go to AnKing note types addon → open it → reset
