For XC43 module I cannot set a lower minimum current out than 200mA. The maximum current cannot be lower than 600mA. this was easily possible with Iqan Design 6.06. Maybe also a firmware issue in XC43? 

This sounds like the normal functionality for limits on the min and max current. 

Select the COUT, bring up the Component navigator (Ctrl-J) and navigate to the Adjust item. 

On the adjust item, you can see the limits that have been set, and change these.

If you do not remember setting limits on the adjust item, it might be that you have selected a Device type on the COUT, that  sets limits automatically.
