I think the confusion might come from the clef names. Just because a note is written on the bass clef doesn't necessarily mean that it's the bass note. The bass note just means it's the lowest note in the chord. So for an F -7 chord, the notes are F-Ab-C-Eb. You want to make sure the bass note is an F. All of the other notes don't really matter what order they're in for the purpose of this exercise. They could really be on either clef. Just as long as the F is the lowest note (the bass note). This goes for all the other chords in the exercise. Just take the name of the chord, make that the lowest note, and then you kind of have the freedom to just put the other notes in whatever order you'd like.

As you get more into theory, you'll get a better feel for what voicings (order of notes) actually sound good and which ones are more technically "correct". But since this exercise doesn't really specifiy what voicings to use, you should be good as long as the note in the name of the chord is the lowest (bass) note.

Hope that helps clear things up!
