Import Novel automatic chapter splitting broken for anyone else?

Chapter splitting seems to be broken right now. When I import a story I’ve been working on (which I’ve divided manually into scenes using headers) it just dumps it into one chapter instead of splitting it up like it usually does.
I checked if it was something about the file by repeating the process for an old story I had already used sudowrite for and the same thing happened.

Anyone else having this issue? Is it a known issue?
Hope it gets fixed soon, it’s doable manually but a huge hassle.
