[Azure OpenAI Service] Latest api version only returns choices content in english

Hello all, I've implementing Azure Open AI with Azure cognitive search, all the information that is indexed in cognitive is in spanish, however after finish the integration bewteen Azure OpenAI and the search service all the responses are in english (no matter the indexed content is in spanish) and all the prompts made are in spanish also.

I'm consuming the following endpoint: **https://.openai.azure.com/openai/deployments//extensions/chat/completions?api-version=2023-08-01-preview**

I'm using api version: *2023-08-01-preview* however if I try with an older version (version: *2023-06-01-preview*) the answer is in spanish (according to the language used in the prompt).

This is an expected bevaviour?

Note: If the prompt contains something like "respond in spanish" the openai service answer in spanish, but I do not think this is a right approach to take because it increase the token's lenght and it's a hardcode solution.

Start by reproducing the Spanish prompt and indexed Azure Cognitive Search content against the 2023-08-01-preview and 2023-06-01-preview extensions/chat/completions endpoints. Compare the responses and determine whether the language difference is expected; document the finding or identify the API specification change needed.
