Thanks for all the inputs, but none worked for me, so spoke to Andy Kunz, he had me go to the system menu and adjust the values under "Digital Switch" that corresponds to the switch/channel. This should have worked, but didn't for me either, since I had another channel, AX3 also actuated by switch B, and would have messed up AX3 pretty badly.

So next, he had me created 3 independent mixes to the each of the positions of that switch to X+8 and this worked beautifully. So conversely, I suppose if I set up Digital Switch from system menu properly for B and X+8, and then pmix AX3, probably would have also worked and would save me a couple of pmixes. He did comment that the Gyro feature of the DX18 should have also worked but he's not that familiar with it, .........and I didn't know that it was even there!
