Wrong temperature when slicing using second extruder only

Vertex 3D Printer Vertex - Printer software (repetier, slicer, ...)

When I slice a print with repetier (cura engine) using the single head setting and selecting the second extruder, the g-code contains the temperature settings of extruder 1 for extruder 2.

It does print with the second extruder (with a offset). When I select extruder 0 for support (even when not using support) the temperatures are correct (but the 0 extruder is heated while not extruding and will clod).

Is anyone familiar with the problem?

To print with the left extruder only do the following :

Select 2:EXTR 2 in the Object Placement" tab.
Select “Single Head” in the “Print configuration” of the “Slicer” tab.
