Describe the bug you're encountering

When return multiple resources to the swagger-ui the inferface only loads the data from the first resource of the list.

To reproduce...

Steps to reproduce the behavior:

1. Create muiltiple resources and create a primary bean that returns them
2. load swagger-ui in the browser
3. only loads endpoints from the first resource

Expected behavior

Loads endpoints from all resources.

No repository file or test is named in the issue. Reproduce the problem in Swagger UI with the Java configuration returning multiple Swagger resources, then trace how the resource list is loaded; done means endpoints from every resource appear in the interface rather than only the first.
