1.3 Level Meter miscalibrated for DAX?

When using audio from DAX, I cannot get the set RF power until the main level meter bar (on the SmartSDR "P/CW" panel) is all the way up to zero and the peak indicator shows way into clipping.  This is new behavior to 1.3.0.

In this particular case, I am using the Tune signal from WSJT-X, which is just a sinewave (1307Hz for my current WSJT-X setting, but the problem does not seem to be dependent on frequency ).

The frequency is 50.276MHz and RF power is set to 50W and I need to bring the level up as shown to get 50W:

If I set the level as recommended (manual section 25.3.3) I get 17W:

There is something going on with the transmit levels.  We have a defect listed for it and are actively investigating it.
