ARM azure template ignores the sitecoreSKU parameter

Hello Guys,

I'm trying to deploy sitecore 9.0.2 XM scaled using Azure ARM templates, tool kit , etc but i can't deploy the SKU mentioned in my file azuredeploy.parameters.json :

 
"sitecoreSKU": {

"value": "Medium"
 
}

 

Everytime i start my script it getting an "extra small" SKU deployed, can you please tell me if i'm missing something?

Thanks a lot guys.
