Hi, How to disable the “downloading resources” at the first game start.

When I install my game via Google Play Store, it downloads the APK and the OBB File (600mb). But when I start the game first time, it downloads again some stuff. I think its again the OBB File (around 600mb).
This is dumb because the User downloaded it before directly from Google Play Store

Does anyone has a fix for that? I think the Problem is a setting in the Android Packaging Settings, but i have really no idea which can cause the Problem
