Starting to learn Japanese again through anki, what to do?

Hey everyone, so I was really deep into learning Japanese a year ago and studied daily for a couple of months, I’ve amassed about 2K words in total in anki and I’m pretty sure I forgot most of them by now, what do you recommend I do. Should I reset all my cards? Is there a specific feature I can use like (a certain custom study mode). I’m pretty sure I was using anki wrong since I read somewhere that I shouldn’t use the “easy” button and and anki isn’t flagging all the words I already studied for review and that I think is because I usually hit the easy button a lot and the interval became 1-2y back then. I’d appreciate any feedback!
