Reading position jumps when re-openned

First I wanted to say I love the app; been a paying use since 2020.

Recently I’ve found that when I close a long book and reopen it later, the page jumps from, say, #20 to #150. If I do it a second time it will jump to the final few pages.

I don’t know if the issue is new; I’ve just started reading long 300+ page books Like Dawn of X a couple months ago.

I’m on version 2.14.1. I flipped through the forum topics and didn’t find anyone else reporting the same issue.

Am I just doing something wrong?
