    INSTANT_CHECKUP_TYPE_CHANGED = 'INSTANT_CHECKUP_TYPE_CHANGED'
}

actual output

export enum ActionLogTypeEnum {
    REGIMENCHANGE = 'REGIMEN_CHANGE',

Command line used for generation

java -jar ./swagger-codegen-cli.jar generate -i ./test/test.schema.yaml -l typescript-axios -o ./test --additional-properties modelPropertyNaming=original enumPropertyNaming=original

Reproduce the issue with test/test.schema.yaml using the stated swagger-codegen-cli command and the typescript-axios generator. Then trace how enumPropertyNaming=original is handled for generated enum member names. Done means the output preserves underscores in the generated TypeScript enum members as shown in the expected output.
