my currently reading got deleted?

has anyone else experienced this , or know if there's anything I can do about it? my currently reading that had over 380+ manhas/manhwas was completely wiped, im kind of at a loss because i had so many i can't even remember them all and I really enjoyed taking 2 week breaks and just catching up on everything. This time I came back from a bit of a longer break and everything I had has been wiped
