Italian Adverbs Lesson 1 Problem

[ziggKogg]

In my lesson 1 of Adverbs, none of my new words get highlighted. Does anyone else have this problem?

I haven't reached Adverbs yet, but I have encountered this problem randomly at several other Italian lessons (not throughout a whole lesson though). Whenever this happened I reported it as a problem. Maybe you'd like to report it too!
