I needed to map out stores for my job in all the different regions. Some of the maps came out fine, others seem to be missing one pin. Before I preview the map, it will tell me that all 18 addresses have been successfully mapped, however, only 17 pins will show up. I have tried manually retyping the document, eliminating columns but nothing seems to work. Am I doing something wrong? Is there a way I can insert another pin? I can figure out which ones are missing, I just can't figure out why.
