Only getting an error on marked line for this code:

@Serializable
data class EmploymentAgreement(
   @Contextual
   val firstEmploymentDate: LocalDate,
   val employmentLevel: Double,
   @Contextual
   val activeFrom: LocalDate,
   @Contextual // Why no issue here?
   val activeTo: LocalDate?,
   val vacationDays: String,
   @Contextual
   val employmentTerminationDate: LocalDate?,
   val employmentType: String,

) {
   @Serializable
   enum class EmploymentType {
      @SerialName("Visstidsanställning")
      Hourly,
      @SerialName("Tillsvidareanställning") // Only this line reports an issue with Ktlint
      Full
   }
}

I guess the rule doesn't apply to parameter declarations? Should it?
