I started a game on difficulty preset 2, thus having the settings of 3 commercial and 3 industrial seaports.
One of the cities, however, only had 1 industrial and 3 seaports, presumable related to the sparse amount of water on this map.
I don't know whether you wish to regard it as a bug or a feature of randomness, but I'm reporting it just in case someone cares
