Villager trading enchantments not showing

The enchanted books I can trade with a librarian villager no longer have a button to show the enchants of the enchanted book. In other words, when I unlock an enchanted book trade with a librarian villager, I can't see what the enchantment for the enchanted book is. In previous betas, there was a button right below the enchanted book for you to tap to show the enchantment, but that seems to be gone in 1.13.0.9. Thanks!
