this is my first time posting although I've had my account for years so idk if I'm doing this right, I figured out you might be able to find all of your lists if when you click on one of the lists even if says zero, if you scroll down to where the tags you used are it will say a number higher than 0 so for example if you click on the yaoi tag you've used in the past it will show you all of the things you saved tagged as yaoi, from then you kinda just have to save them manually again but at least you won't waste time finding titles one by one
