Hi,
The CIFP files are coded against ARINC424-20. I’m not sure what you mean by C because the error message shows an R in the third column. But anyway, both are correct according to the ARINC 424- 20 specification.
C => ATC Compulsory Report Point
R=> Fix used for turning final approach
Please report this to the third-party addon developers so they can implement the correct ARINC 424 version. The coding is accurate so far.
I hope that helps.
