Gyroscope Issue Forces Panoramic View Looking Down?

The first 30 panoramic HDR photos taken were fine, and I can viewed them horizontally. But, the last four photos taken shows the pano looking down (see photo attached), and I cannot for the life of me, figure out how to change the view from looking down to horizontal view. It seems that gyroscope may have gone erratic or something (I have read that the gyroscope should be calibrated once every so many photos, or when you change to another location). Any help or tips on how to fix this problem?
