I had the same problem, I found how to change it in tweaks but can't get the changes to take effect.
I have tried to follow the instructions to 'select all books' (by holding down control & dragging the mouse down the page) as there does not seem to be a 'select all' box.
But where is this 'Update Title sort' box that I'm supposed to tick?
Thanks
And before someone helpfully points out that this an old thread. Yes it is isn't it!
