Issue

When both 0-10v control lines are in use, but when one 0-10v control line dims to 0%, or raised up from 0%, the other line dips slightly in intensity then returns to the programmed level.

Description/Explanation of Issue

Example of this issue:

Load on both Zone A and Zone B 0-10v control wires
Set both levels to 100%.
Dim Zone A to 0%. Zone B will dip slightly, then return to 100%.
Set Zone A back to 100%. Zone B will dip slightly, then return to 100%.

The same issue is seen if Zone B is turned on/off; Zone A will dip then return in that scenario.
