Gio in 3.2 has no control of CEM+ racks

I have a  Gio and an Ion as a Primary and Client in a moving light rig with Net3 Nodes and ETC CEM+ dimmers. When the boards are in 3.2, I have control over all the moving lights, but zero control of the dimmers. After much troubleshooting, we took the boards back to 3.1 and got control of the dimmers back. We are going to program in 3.1, but is this a known problem with 3.2? Any thoughts? Thanks in advance
