Is it a known bug that CPS fails to read the patches on SRA3 profile sheets using a KM FD-9?

The calibration sheet works perfectly but the FD-9 won't recognize the chart layout on the profiling sheet (4096 patches on two sheets), printed on a KM C71hc.

I guess the margins on the long edge are two thin... according to KM, they should be >10mm but CPS pushes the patches quite near to the edge.
