Order of drafts

I’ve just noticed that when I have several drafts saved, the one at the “front” of the list is the oldest, while the newest ones are listed under “x more”.
I could have sworn that it used to be the other way round. Now, while part of me can see the point – it stops you having stuff hanging round if you can see it – you either publish or delete; however, I also find it annoying, as I tend to create a draft, do a bit more research & then post. Other posts are things that I know are going to take some time, so they’re items in progress; which may take some time to finish. Granted, this mayn’t be normal – so how do I get back to what I had before?

I don’t recall altering any settings….
