This is a very annoying issue that I have with my kindle.

FW: 5.14.0.1, jailbroken.

It will open the next chapter instead of where I stopped reading.

Is this the default behavior (I hope it isn't)?

What could be causing this?

All my books are azw3, converted from mobi / epub using Calibre.

This issue is present in every book.
Try putting font weight to 1 (minimum first value) and see if it helps. Such issue happened a long time ago, bot sure if it is the same now
Why would the font weight be the reason for the Kindle opening the eBook at the next chapter? I've never heard of this before.
