how to solve detections showing boxes instead of text in Tensorflow Object Detection API?

I have been working on a project which uses open-cv, ssdmobnet, cocoapi and tensorflow to detect objects. I have given names of objects in label_map in hindi language and trained the model, but when it comes to detection it shows boxes instead of text.What is the possible solution.The detections are correct because i have also used display_name in label_map which is in english to check whether the detection are correct.
