Processing ERROR for Rail PNR in Amadeus

[RSKAY23]

Hello,

A PNR that is being run in our back office is getting the below error:

    <errorCode>8111</errorCode>
    <errorCategory>EC</errorCategory>
    <errorCodeOwner>1A</errorCodeOwner>
  </errorDetails>
</errorOrWarningCodeDetails>
<errorWarningDescription>
  <freeTextDetails>
    <textSubjectQualifier>3</textSubjectQualifier>
    <source>M</source>
    <encoding>1</encoding>
  </freeTextDetails>
  <freeText>ERROR AT END OF TRANSACTION TIME</freeText>
  <freeText>ERROR AT EOT TIME                                                     </freeText>
  <freeText>UNABLE TO PROCESS/SERVICES EXCEED NAMES                               </freeText>

I'm not familiar with what services exceed names means. Would this be something like the table of service carriers is missing the carrier in this PNR?
