Language detection always returns 1 result - microsoft-cognitive

Question

I'm having troubles with getting Language Detection to work. According to the documentation on Microsoft's website I should be able to get multiple languages when the service is not sure about which language the input string was. However, I am always receiving only one language. In my example below I used "Hallo" which is "Hello" in both German and Dutch. Also with other words like "Bier" which is "Beer" in German and Dutch, the service gives only one result, despite the numberOfLanguages Query parameter value of 5.
Am I missing something?
Is the service malfunctioning?
Can someone provide an example which delivers multiple languages as a result?
Thank you for all your help.

The documentation has been updated to explain this.
numberOfLanguagesToDetect: Format - int32. (Optional. Deprecated) Number of languages to detect. Set to 1 by default. Irrespective of
the value, the language with the highest score is returned.
