Hit Command-L (mac) or Control-L (windows) and layout handles will appear (small squares at the top of the system above each measure line. Grab one of them in the 1-4 range and move it toward the left, making the measure tighter. You can adjust all the measures, and when they get small enough to make room for measure 5 it will appear on the system. Alternatively, you could potentially just tighten the pickup measure by moving the measure line at the beginning of measure 1 until measure 5 appears.
