@Georgie W - I've just tried this myself and can see the same behavior so definitely a bug, I will look into why that is. Thanks for reporting this.

EDIT: I can see why this is going wrong, probably always been broken I think. There is an attempt to abort the add/remove action if it thinks there is an error from goodreads trying to process a book. The problem is that when removing a book it doesn't have any code to effectively return success even when it does remove correctly. So it jumps out of the book updating loop which is why only the first book in the group is getting removed. new release shortly...
