Text size for port objects?
 

There are many places on the map marked by the name attached to the port (or town, etc) object on the map.

Some are seen when the map is zoomed out, others you have to be zoomed way in to see. I placed a little port on Truk, along with the name ("Truk"), but it is tiny and shows up only with zoom. I copied what I saw on ports that show up larger at lower zoom, no dice.

What am I doing wrong?
