You can choose what text goes on the top of your Marker Box, the data that is displayed when you click a Marker. By default, the first item in your Info Box will be the full location that was used to geocode the place. Many times that will be what you want, but other times there is a more descriptive name in another field of your spreadsheet. You can designate this field as the title, which will list it in bold at the top of your Marker Box.
Choose Validate and Set Options to reveal your example Marker Box and the set of basic options. Then choose Show Advanced Options. The first in the list at the left is the Title option, which allows you to select any field, including location fields.
