Custom Vision Issue

Hello, Greetings of the day!!!

We're using custom vision for object detection for that we've followed sample from this link https://github.com/Azure-Samples/cognitive-services-android-customvision-sample.

We've done training data and generated TensorFlow Model and from that we've found issue that it's not giving accurate result for that I've attached Image with this email.

Please check and do the needful.
