[mkgmap-dev] maxspeed replacement don't works

Hello, In my style I have a replacement for maxspeed: highway=* & maxspeed=DE:urban {set maxspeed = 50} but this don't works in all cases. The maxspeed is added to the highway-name by the style-rule highway=* {name '${name} (${ref}) (${maxspeed})' | '${ref} (${maxspeed})' | '${name} (${maxspeed})' | '${name} (${ref})' | '${ref}' | '${name}' } see: <http://img82.imageshack.us/img82/9241/urban1.png> why is the DE:urban replaced for this way: http://www.openstreetmap.org/browse/way/4468547 but not for this one: http://www.openstreetmap.org/browse/way/7975270 ? mkgmap version is 1265. Greetings, Chris
