Languages not available in the order wizard

I want to order translations using Transifex Order Wizard but these languages are not available in the wizard. Am I doing something wrong?

It might have 2 reasons for this issue:
Case #1:
When you order translations via our order wizard, only the untranslated content is taken into account and it is being charged. This means that if your content has completely been translated into your project’s target languages, then no strings for translation will be detected by our system and as a result, no target languages will be available under the “existing languages” tab in the order wizard.

Case #2:
In order to be able to submit an order to a specific vendor, the locales that have been added to your project should be exactly the same as the ones that Transifex vendor supports.
