markers in the Mod_GMapFP_Map

Hello, at fist my compliments for the component: it's very cheap, complete and high configurable.
I have a very important question: in my site there is many different map (by category, places, ecc) and it's better i use the module Mod_GMapFP_Map with the "where condition" compiled
But it shows only a marker icon, not as in the component map: it's a bug? Can you solve this problems?
I have the Pro version.

Thank's a lot
