I think from reading on it some more, and catching up on that thread that what you’re referencing was actually fixed in a later firmware release and you should have Parameters 1/2 and 3/4 in sync. I’d try doing either -
Param1 = 1
Param2 = 1
Param3 = 3
Param4 = 3
OR
Param1 = 3
Param2 = 3
Param3 = 1
Param4 = 1
And confirm which of the two matches up with your expected behavior.
