ExampleObject annotation is not working

I have the following annotation setup:

@RequestBody(description = "Send in your requestor id to subscribe", required = true, content = {
        @Content(mediaType = MediaType.APPLICATION_XML,
                examples = {
                        @ExampleObject(summary = "1", name = "2", value = "3", externalValue = "4", ref = "5",
                                extensions = @Extension(name = "6",
                                        properties = @ExtensionProperty(name = "7", value = "8", parseValue = true)))
                        , @ExampleObject(summary = "a1", name = "a2", value = "a3", externalValue = "a4", ref = "a5",
                        extensions = @Extension(name = "a6",
                                properties = @ExtensionProperty(name = "a7", value = "a8", parseValue = false)))

                }
        )
})

And would expect the example to be present in the swagger-ui but I have this:

What did work was the description and the required of the @RequestBody and the mediaType. from the @Content

I use this package: io.swagger.v3.oas.annotations.parameters from swagger annotation 2.0.8 and also not working with the latest at the moment: 2.1.4

Start by reproducing the supplied Java annotation setup in Swagger UI using the reported annotation versions, then compare the displayed result with the expected examples. No source file or test is named; done means both ExampleObject entries and their properties appear in the Swagger UI as expected.
