Make sure the Processor and DEXP are off.  These functions may cause some distortion.  I also flatten out the TX equalizer.  When you get setup make an FT8 mic profile.

Paul I am sure this is being caused by the slider on the DAX menu for transmit.  Put it at about 50% and then control transmit power with the SDR power slider.  That should clean up your signal.

If you run your radio 24X7 it's a good idea to restart DAX each day. If listening in the earphones when DAX gets corrupt a scratchy sound will be heard. The signal in the panadapter will look more like a square wave rather than a single peak. Hope this helps.

Look at your transmit signal on the pan adapter. If it has two or three spikes you are over driving the audio in the flex. Back off the signal by using either the tune power slider in WSJT-X or reduce the Dax TX transmit audio. until a nice clean looking single spike appears. Audio listening can give you a general idea but using the panadapter window gives a much better picture of the modulated signal.
