Map getting cut off

Just curious if anyone could tell me real quick why my map got cut off during processing? The last 2 maps I had processed got cut off - you can see on this one the top part of the field got cut off.

As the growing season progresses, the canopy fills in and everything begins to look very homogeneous (all the same). Also the taller crops blow more in the wind making alignment more difficult. This makes it necessary to fly higher so more shared reference features are in each image to align and stitch with. We would suggest flying at 375 - 400 feet (100 - 120m) with 80/80 overlaps over most crops to assist in better stitching.
