I have done it now ;<. I had planned to add one lesson at a time from "Rapid Literacy in Chinese." I didn't want to be overwhelmed by new vocabulary since I haven't studied Chinese in years.
Tonight I finished Lesson 2 and Lesson 1 and 2 were now listed as DONE. I went into "vocab lists" and then "Sections to Add From" and checked off Lesson 3 to start on it. Lesson 1 now appeared as a lesson to add from. I tried to get back to where I started from and things got worse.
I went into "vocab lists" to list of changes to see if it contained a record of what I had done. Not so. I guess this list is for some other purpose. It didn't look right, though. The headers didn't seem to jive with the data. Maybe, it's just that I don't understand it.
At any rate, maybe I've got myself in the position where I have no new words to review today. I should have taken the warning about not having enough words in the queue to heart. Perhaps this will straighten out tomorrow, at least partially.
