DialogFragment design is looking okay in KitKat and under

Question

So, I created some dialogs that are displaying okay on Android 5.0 and above. However when I tested this on Android Kitkat they are showing a white square above the whole content. Here are examples of what's happening. And this is the code of the dialog with the light blue header.

<?xml version="1.0" encoding="utf-8"?>
