I can see that the Output level will be Input +/- Range (if the Gains are both 0).
When I tried with with a high-level sidechain the Output increased as expected and the Gain meter showed the correct level and numeric value.
But when I tried with with a low-level sidechain the Output decreased as expected and the Gain meter showed the correct level. However its numeric value would not go below -6.02dB. In the second screenshot below it should be -12dB, shouldn't it?

(I reserve the right to have missed something
