Did I f up the list?

Hii I've got a question about the list. I know that people r saying that we'll get them back BUT. Before I realized that my list is missing i added some manhwas to "I'm reading/already read". Will that mess up my list? like the data in the database getting mixed up or something. And the possibility of it coming back ? Sorry im stressed qwq
Btw sorry for my English.
