Ok folks, I found the culprit. This was the first time I used my ix20 on the FG18 which was previously programmed for the DX18. Apparently thinking it would be correct, I activated the "DX18 Compatibility mode" Once I deactivated that mode everything worked as it was supposed to. Apparently the DX18 compatibility mode is for going from ix20 to DX20 for sharing ix20 programs to DX20. Not the other way around. Issue solved!
Thanks for the calls. Andy
