Kindle App Question

RyRy

I have the kindle app on my iPhone, I’ve had it for about 3 years. Yesterday I noticed that books I haven’t read for a while are showing up at the top (where my most recently read/purchased books are) and they are all showing at 1% or a few in the 60% like I have not read them or maybe didn’t finish them. But i read these a while ago and have not re-opened them. Why would these be showing up at the top like this? This wouldn’t be bc I’m getting hacked or something is it? There aren’t any new purchases being made, its just old books being reopened again.
