Based on this, I think my problem is not a "PM" problem but more a hardware problem, there seems to be some communication error between CP Flight MCP and PM. I did try using the "Test" function of CP flight and noticed the same problem. Therefore the issue is with CP flight.
Any idea on how I could resolve this problem?
