Refreshing Access Token

[DaVevi]

Upon sending refresh access token request i only get this in my response
{"access_token":"TOKEN REMOVED FOR SECURITY","token_type":"Bearer","expires_in":3600,"scope":"user-library-read user-read-email user-read-private user-top-read"}.
where in documentation it says I should recieve something like this

{

access_token: 'BQBLuPRYBQ...BP8stIv5xr-Iwaf4l8eg',

token_type: 'Bearer',

expires_in: 3600,

refresh_token: 'AQAQfyEFmJJuCvAFh...cG_m-2KTgNDaDMQqjrOa3',

scope: 'user-read-email user-read-private'

}

Edit:
I should've clarified what is wrong.
I do not receive a new refresh token in my response where docs say I should receive a refresh token aswell.
