Swagger-ui not showing example for query parameter

Hello,

I'm working on a Rest API using java 7 and Spring. I have a Swagger documentation using library swagger-jersey2-jaxrs to generate my swagger.json.
To display it, i'm using Swagger-ui from the dist repository (https://github.com/swagger-api/swagger-ui/tree/master/dist).

My problem is that when i display my Swagger documentation, the query param example isn't and i dont know why. If i try with an "official" json (https://petstore.swagger.io/v2/swagger.json) it is not displayed too.

I have the same behaviour for the query parameter format.

From the https://petstore.swagger.io/ website i have this result (the good one) :

And from the swagger-ui from the dist repository

Some one know how i can display my query param example and format ?
Is that behaviour a normal thing ?

Thank's for your help

Start with the Swagger UI dist repository and compare its rendering of the provided Petstore swagger.json with the Petstore website, focusing on the query parameter example and format shown in the screenshots. Reproduce the display and identify whether the dist UI can render both fields; done means the query parameter example and format appear consistently when the same specification is loaded.
