Manga disappearing from profile

A year ago, I remember going on a spree marking a whole bunch of novels as “want to read”. I picked up reading again and so I came back to this site yesterday and my “want to read” is completely empty. On top of that, I could’ve sworn I left comments (only seen by myself) under some novels noting what chapter I left off on and what was happening last. Those were gone too

I was wondering if it was bc I was inactive for over a year or smthn…? Idk I’m so confused (T_T)
