Adjusting CTCSS Level

In the Flex 6400 using the latest SmartSDR and a 2 meter transverter, when I activate CTCSS in NFM mode the deviation is almost 5 KHz and competes with the voice.  Is there a way to adjust the CTCSS transmit level in the NFM mode down to 0.5KHz like it should be??

See chapter 22 in the SmartSDR Software User Guide.  It describes the deviation as a function of the mode (NFM at 2.5kHz vs FM at 5kHz).
