FreeB X12 files, how many ICD justify a CPT?

Hello,
I am using FreeB to generate claims in X12 format. ICD codes are used to justify a CPT code, but when a CPT code is justified by more than one ICD, the generated X12 file does *only* include the first ICD; the other ICD codes do not appear in the X12 file.

Does anyone know if this the correct behavior for the X12 standard? Can anyone help to elucidate this?

Many thanks,
