I LOST ALL MY SAVED READING AND WANT TO READ MANGA

HELP, I logged right now after some weeks on mangago and after entering I noticed that in my own list a lot of mangas weren't saved as "reading" anymore so I checked my profile and 49 out of 1000(!!!!!!!) saved content are ELIMINATED AND NOW I DON'T KNOW WHAT TO DO HELP I DIDN'T DO ANYTHING DIFFERENT FROM THE USUAL
