Not able to get all processing Jobs in hangfire

Actually I’m trying to get all jobs which are in processing stated status but I’m always getting first job only.
Var monitorDetails=Jobstorage.Current.GetmointeringAPI();
Var JobsCount= monitorDetails.ProcessingCount() // Correct count of jobs in processing ex 3(12,13,14)
Var jobsdetails =MonitorDetails.Processingjobs(1,100)
Returns only job which is started first I.e., 12 // not returning list of all jobs.

Anyone can help me out on this?
