Profile not working with Two Primary

Hi John,
I was implementing the Spring Profile demo, but after annotating PrimaryGreetingService and PrimarySpanishGreetingService classes with @Profile and @primary and activating one of them in application.properties, found that it is not working as expected and giving exception as following

2020-04-08 12:35:06.777  INFO 9432 --- [           main] sam.springframework.DiDemoApplication    : Starting DiDemoApplication on Lenovo-PC with PID 9432 (C:\Users\Lenovo\Spring Project John Thompson\di-demo\target\classes started by Lenovo in C:\Users\Lenovo\Spring Project John Thompson\di-demo)

Description:

Parameter 0 of constructor in sam.springframework.controllers.MyController required a single bean, but 3 were found:
	- constructorGreetingService: defined in file [C:\Users\Lenovo\Spring Project John Thompson\di-demo\target\classes\sam\springframework\services\ConstructorGreetingService.class]
	- greetingServiceImpl: defined in file [C:\Users\Lenovo\Spring Project John Thompson\di-demo\target\classes\sam\springframework\services\GreetingServiceImpl.class]
	- setterGreetingService: defined in file [C:\Users\Lenovo\Spring Project John Thompson\di-demo\target\classes\sam\springframework\services\SetterGreetingService.class]


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

The code I have used is from intro_to_profiles branch and I am using Spring Boot 2.2.6. What could be the reason if all steps are followed correctly ?
