Fanspeed for Bridge-Perimeters

Hi everyone,

I'm new here and I am also new to 3D printing. So please be gentle if I am doing something wrong

I am using the "German RepRap Neo" with Slic3r 1.2.9 and I am trying to print some testing-bridges. The problem I am experiencing at this moment is this:

When the printer starts to print the bridge, than I does it with the correct moving-speed, but not with the correct fan-speed. The fan-speed is set to a very low speed, but only as long as the perimeter are printed, as soon it starts printing the infill of the bridge, the fan goes up to 100% as it should already be with the bridge-perimeters. Is this a software-bug or did I miss some settings?

When I set the speed manually to 100% for the entire bridge in the gcode before uploading/printing it, it is printed nearly perfect, but if not, it is just a mess.

I hope someone can help me

I attached the STL- and GCODE-File of the bridge if this helps you somehow.
