Initially, I skipt this one because I didn't understand a section of the notation, but in looking at a different Telemann score (I think it was the two menuets from TWV 55:C1) and comparing it to a modernized version, I realized what it means. At the end of the A section, the note in the right hand is the same both times, but the notes in the left hand are different. Telemann writes out the different notes, but he doesn't bother with the one that's the same, and I hadn't understood the blank measure.
