Sidekiq not processing more than one queue

Question

I have successfully configured Sidekiq for my use but now it is not processing more than one queue. It is only processing the queue that is written first in configuration file. For instance:

---
:verbose: true

:concurrency: 100
:pidfile: tmp/pids/sidekiq.pid
staging:
  :concurrency: 10
production:
  :concurrency: 20
:queues :
  - [kritikal , 5]
  - [critical , 4]

In this case it is only processing kritikal queue. And in following case:

---
:verbose: true

:concurrency: 100
:pidfile: tmp/pids/sidekiq.pid  
staging:
  :concurrency: 10
production:
  :concurrency: 20
:queues :
  - [critical , 4]
  - [kritikal , 5]

It is only processing critical queue. Could anyone tell me where I could be going wrong?

I do not know whether that was the problem but I synced my client and server redis configuration, removed space again from :queue : and restarted my system and Voila!! it is working now. Though I personally do not believe that syncing redis server was a problem because one queue was getting executed in any case.

Sidekiq.configure_server do |config|
    config.redis = { :url => 'redis://localhost:6379' }
end

Sidekiq.configure_client do |config|
    config.redis = { :size => 1 }
    config.redis = { :url => 'redis://localhost:6379' }
end
