application.properties is ignored, taken from somewhere else

Question

I am having a strange issue (i am new in spring-boot), this is my application.properties

server.port=8087
spring.datasource.url:${DB_URL}
spring.datasource.username=${DB_USER_NAME}
spring.datasource.password=${DB_PASSWORD}
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=update
spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.jpa.show-sql=true

When runing it localy, it works just fine. BUT when using a staging server, the changes on the code (controller for example) is taken, but the changes in application.properties is not! server.port for example on my local machine is 8807, but on the staging server is 8080.

Is there some place that the application is taking configuration from?

Thanks for your help

There is a documented list of sources properties will be loaded from and in what priority.

application.properties is at priority 14 of 17, where 1 is highest priority
