For the Mutant Subclass, there's a mistake on the Character Sheet's Short Description for the Mutegencraft section, which states the following:

"You can consume a mutagen with a bonus action, whose effects and side effects last until the end of your next rest."

This is incorrect, as clearly stated in the Long Description: 

"As a bonus action, you consume a mutagen, whose effects and side effects last until you finish a short or long rest unless otherwise specified."

Additionally, some of the Blood Curses have no Short Description is the Character Sheet, while other do. Blood Curse of the Marked is one example.
