What controls the 'Level' setting in SmartSDR?

I've noticed that the SSDR Level  slider seems to have changed it's setting value.
Previously when operating digital modes, the 'green bar' went to about mid scale. Almost exactly under the V in LEVEL.
Now the 'green bar' goes higher to not quite the -10 mark.
My Dax TX Gain setting at 1/3 of the scale.
Obviously I changed something to make the Level increase or go from 'green' to slightly yellow???
Obviously my digital mode operating is via DIGU @3.0K bandwidth.
As there hasn't been any 'upgrades' I can't see what changed.

I incorrectly said 'Level Slider', that should have been 'Level Indicator'

Bill,
  For digital modes (DIGL,DIGU)  via DAX, the 'level' is controlled external to SSDR.   The level can be changed in the DAX Control panel for the DAX channel in use. Or some digital programs have a TX level control that will also effect the level indicator..   .. It you are talking about what the 'level' indicator has to be to get say 40 watts out, then there was a change in the firmware a couple versions ago that changed 'level' vs. power output.   As it is now, a -10 on the level indicator will somewhere in the neighborhood of 10 watts out.    The only other thing to watch out for is if you happen to be in USB/LSB with the DAX button enabled, then the output vs. level is also modified by PROC and/or EQ.
