that sounds not wrong: at this stage they don't need your work contract and Deutsch certificate as they only decide whether to grant you asylum or a right to stay:
The medical documents become relevant if they deny asylum. Then maybe you will be allowed to stay all the same due to your healt reasons (you could get a "Duldung" pursuant to § 60a AufenthG).
The work contract does not give you a right to stay at this stage only if you get a "Ausbildung". Nor does the language certificate.
