Android : Navigation drawer forces app name and icon to appear shortly on startup

Each time I start the app, the application name and icon appears very shortly on the left side over the drawer icon. This ruins the look of the custom ActionBar style.

How can I remove it? I already tried the top solution from StackOverflow, but they all refer to completely hiding the ActionBar. I don't want to hide it as I need it. I just don't know where to turn off this irritating display.

Note: I've let the Android Studio create the Navigation Drawer project for me so all the ocde came from the default creation.
