springboot when I use spring_profiles_active in environment, springboot starts with 2 profiles

• Spring Boot version : v2.2.2.RELEASE

application.yml

spring:
  application:
    name: config-server
  profiles:
    active: dev

---
spring:
  profiles: dev
---
spring:
  profiles: test

before start, I set envronment by

export SPRING_PROFILES_ACTIVE=test

,then I start my app by java -jar app.jar

I got a boot log:

2020-01-13 17:21:17,614 INFO  xxx.ConfigServerApplication:655 - The following profiles are active: test,dev      

But I expect only test profile.

I have tried 2.0.1.RELEASE which works fine.
