Swagger UI does not show all the controllers of my project - spring-boot

Question

I have few controllers which have the same request path prefix i.e.
/v4/users/{userId}/
And then the methods in the controllers are annotated with separate path mappings. The swagger ui shows only one of those controllers.
#Component
public class BaseController {
}
/******************/
#RestController
#RequestMapping("/v4/users/{userId}/payment")
public class PaymentController extends BaseController {
#RequestMapping(value = "/initiate", method = RequestMethod.POST)
public HttpEntity<Object> initiatePayment() {...}
#RequestMapping(value = "/success", method = RequestMethod.GET)
public HttpEntity<Object> success() {...}
}
#RestController
#RequestMapping("/v4/users/{userId}/preferences")
public class CustomerPreferencesController extends BaseController{
#RequestMapping(value = "/deals/{dealId}", method = RequestMethod.POST)
public HttpEntity<Object> favouriteDeal(...) {...}
//some more methods
}
There is one more controller that has the same path prefix i.e. /v4/users/{userId} which shows up on swagger-ui but not the above two controllers.
