Update entity response body is text instead of json

I am updating entities via put request through the API and the responses from Acumatica are returning in text format instead of json even though I have added the accept header for application/json in the request and the response header specifies that it is in json format. With get requests for entities and put requests to get data from custom endpoints, I am getting json as expected. Does anyone know if this has been fixed in later versions of Acumatica? We are currently using 21R1 but plan to upgrade to 23R1 soon.
