Clearance in Copper Pours not applied during CAM export

I have found a problem with the clearances set with the clearance matrix during CAM exports. The clearances set between different net classes are properly cut out of the copper pours in board view and the previews in the CAM Processor.  When processing the CAM job however, neither gerber nor ODB++ files show the copper areas and traces as they are in the board view / preview. 

 

This happens with signal traces within a copper pour, aswell as an polygon adjacent to the signal, aswell as with copper pours of a different signal of higher ranks within a different polygon.

 

This picture shows one example trace on the top layer, inside a polygon and with an adjacent polygon, each a different signal of different class:

The preview window in the cam processor showed it correctly:

But after processing the job this was the resulting gerber:

I already tried different CAM job files but there was no difference. Saving the design and restarting also had no effect. So I don't know what else to try to get the output I need and it feels like a bug in the software.
