"Principle Procedure Flag (v4)";"Principle DIagnosis Flag (v4)"
"Principle Procedure Flag (v4)";"Principle DIagnosis Flag (v4)"
You will see that the Procedure flags got described as Diagnosis flags.
Incidentally, there's a spelling mistake in c_name and c_tooltip. It should say Principal Procedure, not Principle Procedure. For reference, please see OMOP CDM 4.2 permissible values for PPX:
P=Principal
S=Secondary
