Hello,
TARGETING_SETTING_DEMOGRAPHIC_CRITERION_TYPE_GROUPS_MUST_BE_SET_TO_TARGET_ALL
Starting with AdWords API v201802, TargetingSetting must not explicitly set any of the Demographic CriterionTypeGroups (AGE_RANGE, GENDER, PARENT, INCOME_RANGE) to false (it's okay to not set them at all, in which case the system will set them to true automatically).
