I don't know if the latest report was accurate, however there is nothing difficult about your question.

There are millions of people defined as "not in the labor force" for whatever reason -- they don't work, and are not looking for work. Any of them at any time can 1) start looking for a job, which makes them become "unemployed" 2) or actually get a job, which makes them "employed"; 3) or get a part time job while claiming they want a fill-time job, which puts them in the U6 category. Any of these actions moves them from being "not in labor force" to being in the labor force.

That means the numbers of employed, unemployed, U6, and labor force are all basically independent and can change together or separately. There's no reason to think unemployment cannot drop if U6 remains the same or increases or whatever.
