Thank you for your prompt reply- it works and now I can see some cards.
The problem now is: I unsuspended two tags under the step1v12, which are pathoma and sketchy micro. However, I could not see these two subdecks (not sure if this is the right word). The only deck shown on the main page is “Anking overhaul for step 1 2”, as the pic shown below.
The ideal scenario for me would be that I can use the Anki deck for pathoma when watching pathoma videos and use the Sketchy micro deck when watching sketchy videos. Now it seems all the cards are mixed within the “anking overhaukl for step 1 2”, leaving no options to choose a specific subdeck.
