maxResults not working, seems to alwaysDetect max of 10 objects

[SpicyVision]

I am testing the Google Vision API and trying out the OBJECT_LOCALIZATION feature,. But this seems limited to 10 objects. Even if I increase maxResults to 50 or any number, I always get a max of 10 objects detected.

"features": [

        {

          "type": "OBJECT_LOCALIZATION",

          "maxResults": 50

        }

      ]
