two api not showing in swagger list

Hi, 

Could you please help, this is a very urgent issue. 
In the swagger API list, two API does not list out. I couldn't whether it's not satisfy the swagger generation spec.
sample list 
[RoutePrefix("api/Students")]
[Route("{id}/V2")]
[ResponseType(typeof(studentModel))]
GetStudentV2(int id,bool isB2B=false) ==> Method name
id required and isB2B is optional

[Route("{id}/V2")]
[ResponseType(typeof(studentModel))]
GetStudentGroup(int id,bool isB2B=false) ==> Method Name
id required and isB2B is optional

Could please help me with this
