Reset all card sets to initial state

user comment: "I'm learning words, but I haven't had a chance to learn them for a couple of months. Now, the section where I can learn words has accumulated more than 120 words. When I start learning, it gradually displays all 120 words, and I'm getting confused because there are so many words. I usually added 4-⁠5 words a week and was able to learn them, but now it seems impossible to process so many words. When I try to reset my progress, nothing special happens. I created my own card lists, and if I start learning a word, I can either keep it in the Learn section or delete it in the Delete/Know section. I'd like a reset function for all or specific card lists. For example, if I'm learning words and have accumulated more than 600, I can't physically go through them every day. There are words I've forgotten—a progress reset function is very important. It should be like when you initially enter the card list, not like you're unfamiliar with everything and then add a little at a time."
