As the second sentence at the top of the page states, "Types that have
multiple parents are expanded out only once and have an asterisk".

In short, this is not a duplication. FireStation only appears once (at
http://schema.org/FireStation) but is both an EmergencyService and a
CivicStructure. 

http://schema.org/docs/datamodel.html also says: "We have a set of
types, arranged in a multiple inheritance heirarchy where each type may
be a sub class of multiple types."

So this is working as designed.
