Hi Carlo,
'Trial Phase' codelist used to have terms in Mixed character case until version 2014-12-19. Since this version all terms of the codelist were changed to Upper character chase. Please ensure that you are using correct CT version for validation.
Kind Regards,
Sergiy
These rules seem to be firing for the trial phase codelist due to letter case mismatches. The relevant Pinnacle codelist metadata (OID = "CL.C66737.TPHASE" and OID = "CL.C66737.TPHASE.CD") appears to have all of the values upcased, but the CDISC published terminology for codelist C66737 has mostly mixed case values.
