Why is it so hard to delete a book?

The interface is indeed much prettier now, but when I try to delete something, its just... SUPER HARD... Basically, the delete button doesnt appear when I swipe left, and even it does, it disappears after a millisecond. Deleting multiple books at the same time doesnt really work either... Cuz it doesnt respond when I tape on the minus sign... This is super annoying :( please fix?
