I couldn't find anywhere to post errata and don't have much more time to browse tonight so decided to post it here and hope someone catches it.
In Basic Bootcamp - Self Introduction/Basic Greetings in German Lesson 1 on page 3 near the bottom it says:
'Freut is the inflected verb form, third singular person, present tense of the verb heißen ("to be called")'
where they intended to say "freuen" instead of "heißen".
