Quick Control dials not moving in Halion when multliple instruments loaded

When multiple instruments are loaded into a Halion instrument track the quick controls still work but the dials on the Halion quick control panel do not move.
The quick control dials on the Cubase instrument panel move correctly.
If I put my mouse pointer over a Halion quick control dial and turn the corresponding dial on my controller a tooltip shows the value changing but the dial does not move.
