When the Client does not have an application.properties file, Server Eureka does not recognize the default name

[7zism3]

I am setting up Eureka for the first time: I have 2 Clients registered with 1 Eureka server. 2 Clients only use the application.yml file, and do not use the configuration

eureka:
  instance:
    appname: xxx

Now the Eureka Server recognizes 2 Clients with the same name.

If I add an empty application.properties file, Now the Eureka Server recognizes 2 Clients with different names, which are the names I declared in the application.yml file

spring:
  application:
    name: xxx

Please see the attached image for more information

I'm working around this by adding an empty application.properties file. But it's not pretty.
