What's going on ??? Help

So all of my "my reading" and " I want to read " manga got put into my already read tag, it's been a while since I've been on the website because I've been busy with school so I'm not really sure what's going on.
I really had a break so I My phone had to catch up on some of my mangas and not I have 1000+ in my already read for some reason and 3 in my now reading !!!
I haven't been able to find much info so I'm wondering if I have to go through and read tag/ sort everything or if it will fix itself ༎‿༎
