Inverse WAV setting & Weird Dashboard Results

I have a Right & Left WAV. My Right WAV is set up as the Inverse of the Left WAV for each Point along the line:

Attachment 8017

Yet on my Dashboard it shows it OK and at 99% while Left is at its programed level 2%

Attachment 8018

And the FLO and RPM are reported at nearly twice the Left WAV. Is the Dashboard wrong? Or have I set them up wrong?

Ok, I discovered that Inverse should not be used with Constant which is what the setting above was at. I changed each of the Constant/Inverse settings to Constant/Mirror and that cured to the problem.
